I have UEFI (which I just learned), but grub-pc is installed. I assume that's because the UEFI has legacy mode turned on.

Can I move from grub-pc to grub-efi-amd64? There are a few random webpages that suggest it's difficult; I haven't found an authoritative source that says how to do it.

I didn't notice anything in the gnu.org help-grub archive that seemed relevant, but I may have missed something.
