Hey

I am trying to get secure boot to work in windows 11.
No matter what I do Device Security shows "Standard hardware security not supported" and Secure Boot State in msinfo32 says Off

I've tried:
Disabling and enabling Secure Boot in BIOS
Clearing keys
Loading HP Default Keys
Clearing TPM in windows.
All drivers updated via HP Support Assistant.
Windows fully up to date.

Tried resetting the BIOS by removing the power and holding the power button for 30+ seconds.
Flashed the BIOS 3 times.
Tried holding down Windows key and B for BIOS reset during boot.


BIOS keeps saying Platform Key Not Enrolled.

BIOS Version fV22.Rev A
OS 24H2 26100.4770

 

I am sure this happened after applying the latest BIOS
Is there an issue with F.22 Rev.A?
