Hello HP Support Team,

I own an OMEN by HP 40L Gaming Desktop (Model: GT21-0xxx), and I have accidentally cleared the Secure Boot keys from the BIOS. Since then, Secure Boot has been disabled, and I am unable to re-enable it because the OEM factory Secure Boot keys are missing.

I have tried performing a BIOS recovery using the official HP BIOS recovery USB method, but the factory Secure Boot keys did not restore. The Secure Boot option remains grayed out or disabled in the BIOS.

Could you please assist me with restoring the original factory Secure Boot keys for my system? If there is a special BIOS reflash or utility to reprogram the keys into the firmware, I would appreciate your guidance or provision of the necessary files or steps.
