Question about BIOS Access

I have noticed on my Qubes desktop that after a period of time I am no longer able to see the BIOS boot screen, nor boot into the BIOS during startup. I can clear my BIOS to make BIOS access available again. This has happened a few times, with BIOS access disappearing after a few weeks or so.

Question 1: Is my system being hacked?

Question 2: After clearing the BIOS to regain BIOS access I can no longer boot into Qubes (drive not shown). Is it possible to clear the BIOS and regain access to my Qubes system without having to reload Qubes?

You can restore EFI entry like this:

You can also use EFI fallback bootloader path EFI\boot\bootx64.efi so you’ll no longer have to restore EFI entry in the future

Copy files from /boot/efi/EFI/qubes to /boot/efi/EFI/BOOT and in /boot/efi/EFI/BOOT change filenames grubx64.efi → BOOTX64.efi and grub.cfg → BOOTX64.cfg

Thank you!
