I'm just guessing, but can you dump the RAM adapter and remove the RAM portion from the dump to get an 8KB BIOS?

I'd imagine the same as any other NES/Famicom game. The last 8KB is the part that matters, as that is the BIOS.

Probably anything that can dump Famicom cartridge games.

I meant the BIOS. What tool can I dump the BIOS with?

KingMike is correct. You use whatever is used to dump Famicom cartridges to dump the FDS' RAM adapter and keep the last 8 KB.
