 To make sure that we are on the same page and I totally understand you.

 Say I burn a DVD with the debian bootable iso (the live DVD) for
amd64, arm64 and 64-bit risc-v processors, will GRUB2 automatically
detect the architecture and pick the file?, or, as I suspect, you will
have to cook some configuration file?

 Any examples or leading information about such GRUB2, multi-boot off
a live DVD "prior art", "trodden path ways"?
