as title written, TB3 cannot be found in Device Manager, while already enabled in BIOS (1.30):
The ERROR is 0x208: SDK_SEREVICE_NOT_FOUND service doesn't exist, what service is expected?
Could anyone show a screeenshot with TB3 enable in device manager?

I didn't read all of your post, but I assume this is part of what you're looking for.
Under "System Devices"
Also, AFAIK, the TB3 controller itself is responsible for regular USB-C functionality on those two ports (though not USB-C PD [charging] that is handled by a seperate PMIC). So if the USB-C ports work with a flash drive, for instance, then the TB3 controller is working at some level. Charging is handled seperately (even though they are using the same ports), and I don't remember what the TB3 controller's exact relationship with USB-C DP Alt Mode was, so I don't dare comment on that.
EDIT: for clarity, I should note I have the charger plugged in right now, along with an USB-C --> DP cable, driving an external monitor. When I briefly unplugged both devices, the TB3 controller seemed to still be present in the device manager, though I cannot guarentee that's an accurate assessment.

Thanks Jeremy for the screenshot.
That would be a successfully installed TB3 as result in Device manager I am aiming for!
Currently I am using a USB-C hub with Gbit Ethernet & USB3+PD-USB-C, plugging into the USB-C/TB3 port, but still TB3 is not showing up.
On the other side, I also notice you have System Interface Foundation V2 device successfully installed, which is pre-requested for ThinkVanatage to function, but I don't know those 2 are related.
Anyways I still need to further investigate why my TB3 not show-up, hopefully a Lenovo expert could share insights here.

I have a similar issue. My X1C6 does not show the following in device manager under system devices. I have tried everything and it will not show up.
Intel(R) Serial IO GPIO Host Controller - INT344B Intel(R) Serial IO I2C Host Controller - 9D60

Thunderbolt BIOS Assist Mode (the BIOS setting shown in the screenshot of the original post) should be set as DISABLED. Enabled (as shown in the screenshot) is not compatible with Windows 10 1709 or later. This is why the Thunderbolt device does not appear in Device Manager.

Thanks. How do you uninstall these two software and reinstall them? I think I have uninstalled Thunderbolt software and reinstalled it. But the device still not shown. I may need to uninstall the foundation? Thanks again.
