If the ACPI driver is no longer available for download for Windows 10 and it was previously, it was most likely removed. There had been confusion over whether that file actually updated the driver as there was no on-screen acknowledgement that it had completed the update. In your situation, go into Windows Device Manager and look under the System Devices heading to see if there are any exclamation marks or unknown devices listed. If there are none then Windows maybe using a native ACPI driver that is built into Windows 10.
As for Conservation Mode, that option is now included with the Lenovo Settings app. If you do not have it install then visit the Windows Store and do a search on "Lenovo" to find it.

No, don't uninstall it. Just leave it. If you didn't download and install a ACPI driver then Windows is using the Lenovo driver that was included with the Windows 10 installation.
If you are concerned about having the latest version of that ACPI driver then right click on its listing in Windows Device Manager and choose Update Driver from the menu. On the next screen then choose Search Automatically. Windows will then search for a newer driver and install it if there is one available.
