Enhanced sound effect tab is missing in Realtek HD Audio Manager on my Thinkpad P51.
This is a screenshot I found on Internet showing the sound effects tab:
I went to Control Panel\All Control Panel Items\Realtek HD Audio Manager, open the GUI, saw only speaker and microphone tab. Please see the attached screenshot.
I have tried:
1. uninstall/re-install device and driver
2. update driver
3. download latest driver from Lenovo support site and install it
None of above resolved issue.
Would anyone experiencing the same issue please provide a solution? Thanks in advance.

Hadn't noticed this before now, but you're right. The "original" Realtek HD Audio Manager GUI did have those extra tabs. But I have now looked at both my Win7 and Win10 versions for my P70, which have both been updated to the latest version 220.127.116.1124 driver, and those extra tabs are gone.
Lenovo uses the same Realtek ALC3268 HD Audio Codec in all of these P-series machines, both in my P70 and in your P51. So I'm surprised that the old GUI has apparently been changed. I have the same thing you have, both in Win7 and Win10.
However also in Control Panel is a Dolby Audio object, which I believe is where the equivalent functionality previously shown in the no longer present Realtek HD Audio Manager tabs is available.
In the Dolby app there are built-in presets for Dynamic, Movie, Music, Game and Voice "special effects", although there isn't a way to actually see what the "virtual EQ settings" are for each of those presets.
But if you click on the "Personalize" tab, you will now have the opportunity to adjust a 20-band EQ, as well as turn on or off (a) Surround Virtualizer, (b) Dialogue Enhancer, or (c) Volume leveler.
Now interestingly, looking at the way Realtek HD audio is implemented in my ASUS Z170-Deluxe desktop motherboard which uses the Realtek ALC1150 HD Audio Codec, it looks like ASUS customized the audio software from Realtek into their own Realtek HD Audio Manager app in Control Panel. It looks very sleek and has a "dark theme", but it also has the old extra tabs you were expecting. I have my own custom EQ settings in effect, for my Altec-Lansing 4.1 speakers.
I think Lenovo has de-coupled its implementation of extra-tab Realtek HD Audio Manager and gone back to the basic minimalist Realtek interface, relying on the Dolby Audio functionality to replace the similar and now removed Realtek sound effects functionality and capability.

Unable to find any Dolby Audio Object functions on my P51. Have searched Device Manager and Control Panel. Only Realteck shows up. Am I missing something?

Don't know. For me it was automatically created as part of the Lenovo audio driver download.
Assuming you're using Win10 I would say this is where the latest driver for the P51 is to be retrieved.
On my machines, there is a C:\Program Files\Dolby folder, which I assume gets built from this audio driver install.
And as my screenshot showed, there is definitely a "Dolby Audio" object in Control Panel for me on my P70, both in Win7 and Win10.

I downloaded the above link and after install I still do not have Dolby Audio showing up in my Control Panel.
I did the search "C:\Program Files\Dolby" and here are the results... I don't know what to do with this file..

After researching Realtek/Dolby Audio issues, I have a basic question...Does the P51 support/have Dolby Audio v2/4
capabilities and does it come from the "Factory" with Dolby Audio installed?

Went to Lenovo support and searched for Audio Drivers. The only driver found was for Realtek. No driver shown for Dolby Audio for P51. Talked to support and had them read all of the forum threads for this issue and his suggestion was to search for Audio Drivers in Lenovo support for any missing Audio Drivers.
It appears Lenovo has opted NOT to pay royalties to Dolby for Dolby Audio for the current P series ThinkPads.

Thanks to DSperber for his hint that Dolby Advanced Audio console is decoupled from the Realtek HD Audio Manager. I found out below solutions to get Dolby Advanced Audio console back to Windows Control Panel:
Go to Lenovo official driver download site, search product P51, select type 20HH, find Realtek High Definition Audio Driver for Windows 10 (64-bit) - ThinkPad P51 (Types: 20HH, 20HJ), P71 (Types: 20HK, 20HL).
Install above driver.
Install C:\DRIVERS\Realtek Audio Driver\PCEE4\DolbyAdvancedAudio.msi
Find Dolby Advanced Audio in Control Panel.
Altoid666, you can try this solution.
One thing I noticed is the sound effect profile does not seem to be working. I defined one as above, but the output made no difference.

Well, this is all very strange. The results with my P70 are certainly different.
(1) Looking at the README details for the Realtek Audio Driver for the P51, it is version 18.104.22.16858 dated 12/12/2017. Initial version was 22.214.171.12445 dated 3/13/2017.
In contrast, the latest driver for my P70 is version 126.96.36.19924 dated 8/22/2017. There's mention of a fix with version 188.8.131.5217 dated 4/19/2017 that applies to a Dolby vulnerability. There's no such mention of this in the README for the P51 driver.
Both README's have a trademark mention for Dolby Home Theater v4 at the bottom.
(2) I completely uninstalled the Dolby items I found in Control Panel -> programs. I also went into Device Manager and "uninstall device" for the Realtek High Definition Audio. Then I re-booted.
I then ran the downloaded latest P70 Realtek Audio installer file (184.108.40.20624), which unpacked itself into c:\Drivers\Win\Audio and ran. It did not unpack itself into C:\Drivers\Realtek Audio Driver (which doesn't exist at all), but rather only seemed to show folder title information for the Dolby Audio package. But the Realtek driver installer files are located in a separate Win64 folder.
(3) After the install completed and a reboot, sure enough both Realtek HD Audio Manager and Dolby Audio are shown in Control Panel installed programs.
(4) The Dolby Audio programs went into c:\Program Files\Dolby\Dolby DAX2
(5) The GUI you show for Dolby Advanced Audio v2 that you got by manually installing that MSI file is not v4 as the README trademark shows. Also, it is an older GUI that I recognize (it might be the version used on my older W530 laptop, I'll go check that in a bit) but it's not the version I now have on my P70 from this install (see my earlier screenshots).
The installed Start menu properties for Dolby Audio shows "C:\Program Files\Dolby\Dolby DAX2\DAX2_APP\DolbyDAX2DesktopUI.exe" (I use the START10 product, to give me a Win7-style Start menu).
