I was finally able to block the Lenovo 188.8.131.52 firmware update using the Microsoft Show or Hide Updates tool and break this vicious reboot cycle.

There is definitely a problem where X1E and P1 gets downgraded to 1.23 by Windows Update and we are investigating it. Sorry for this trouble. Here is some more information:
1. BIOS has always been in Windows Update, since at least 2017.
2. Windows Update will only push BIOS updates if you are in insider program.
3. You can prevent BIOS update initiated via Windows Update by changing the BIOS setting in Security -> UEFI BIOS Update Option -> Windows UEFI Firmware Update.

Thanks for the new information. Given that the track record on recent BIOS updates has been a bit shaky, wouldn't it be advisable to set the UEFI Update in the SECURITY BIOS tab to DISABLED as the default?
