How to I change the white new BIOS to the old legacy one? The new one has the secure boot setting  disabled in my case. In the hp tutorial, it only shows how to disable secure boot using the old bios.

It seems the secure boot enable/disable setting is not available if UEFI native boot mode isn't selected or if "Clear safe boot keys" is ticked. Is switching back to old bios unavailable?
