Secure Boot Violation – Invalid signature detected. Check Secure Boot Policy in Setup

[ZigZagMan]

Secure Boot Violation – Invalid signature detected. Check Secure Boot Policy in Setup  with a GT22-0139 Omen Gaming 45 . Happened a few days ago  ,  and since it does not access the secure boot , it does not see the hard drive ( next screen is F0 erroR for the hard disk , which is working )

Tested all , No hardware issues , replaced the CMOS battery ,  but the only way to start windows is to disable secure boot ..The logs in tests show the date is 2021 , but there’s nowhere to change the date in the Omen setup utility .

In the BIOS menu , my only option was to clear the Keys but not to upload  or restore factory keys . I also updated to the latest BIOS , no change . How or where to get this restore keys function activated ?  is there another menu other than the Omen setup that can be used ?

Thanks
