B650 GAMING PLUS WIFI TPM ATTESTATION BUG

[babkafo159d02e4]

Hello
I have MSI B650 GAMING PLUS WIFI motherboard with Ryzen 7 7800X3D.
TPM is enabled in BIOS (AMD CPU fTPM), Storage: Ready, but Attestation: Not supported.
Manufacturer version: 6.32.0.6
Specification version: 2.0
I tried:
- Latest official BIOS (already updated to the newest version)
- Disabled/enabled fTPM in BIOS multiple times
- Cleared TPM in tpm.msc and full reboots (Shift+Restart) several times
- Secure Boot: Enabled (Standard mode), UEFI mode, SVM Enabled

Attestation still "Not supported". This causes issues with some anti-cheats (FACEIT, etc.).

Can u give some advice or answer bc i lost 15h on this and still dont know how to fix this

Current BIOS version: 7E26v1x

Thanks!

Try run the following 3 commands using powershell (Admin mode)
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x5944 /f
Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"
Manually reboot the system when the AvailableUpdates becomes 0x4100
Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"

Re-flash to this BIOS version E7E26AMS.1MA
then re-test.

I installed your BIOS and tried to enter your commands in PowerShell, but it still didn't work.
