That's the only feasible approach at the moment. IMAGE_FSTYPES gets
checked while inheriting the class and then triggers inheriting
image-live.bbclass even when the "live" type gets removed later one.

There's a patch for x86-base.inc which removes this unconditional
extension of IMAGE_FSTYPES, see "[OE-core] [PATCH] x86-base.inc: Don't
add live to IMAGE_FSTYPES, default instead".

You still need to set some kind of IMAGE_FSTYPES, for example "wic".

Further hacks may be needed depending on your version of OE-core, for
example inheriting the class set by EFI_PROVIDER.

Here's how we solved this in refkit:
