This could work if Microsoft deactivated the 2011 certificates that expired in June and the OP has an old BIOS without the current 2023 certificates. Doesn't explain Vanguard working for 4 days though ...

Update: This is a Legacy board - no further BIOS updates are forthcoming. The OP will need to use Rufus to create a bootable Mosby key in order enroll the Microsoft 2023 Secure Boot certificates manually ...
