Can I convert a boot disk from BIOS to EFI (UEFI)?

I have a BIOS MBR (Linux) on my NVME - it works fine.

I'm now trying to enable SAM (or Resizable BAR) and in order to do so I have to disable Compatibility Support Module (CSM - i.e. BIOS) from my motherboard (ASRock Taichi x570).

The challenge is that if I do the same, my NVME doesn't get identified as bootable device of course.

Is there a way on Linux to convert the MBR from BIOS to EFI (or UEFI)?

Thanks!


As pointed out can be done - but is quite a potentially cumbersome process. The main suggestion is to format and reinstall Linux.
