I'm unable to disable TPM/PTT at the BIOS level - FNCML357 - NUC10i7FNH

Hi,

 

This is Visual Bios FNCML357.0039.2020.0312.1734.

Intel Nuc NUC10i7FNH

Processor: i7-10710U

 

I have disabled Intel Platform Trust Technology in Visual Bios, but upon loading Windows, TPM is still active and showing up in Device Manager while it should not. Basically the checkbox isn't having any effect.

 

Some bitlocker setups depend on TPM being disabled at the BIOS level, which changes Windows behavior to put a full length password as key, and intentionally prevent the computer from booting if the password isn't known.

 

This is a fresh install, Windows 10 - Build 18363.

 

Can this checkbox be resolved in BIOS accordingly, so that Windows doesn't see a TPM device when this checkbox is disabled.

 

I've attached pictures to demonstrate the issue.

 

I am available to test a BIOS fix to confirm it works.

Hello WMaal,

 

I work with Wanner and after looking into this issue for some time, we believe this is a bug in BIOS and we are filing an internal bug report to get this issue addressed, hopefully on next BIOS release.

I apologize for the inconvenience caused and thank you very much for reporting. I will keep you updated on any progress we make.

 

Regards,

Ronny G
