That's not possible.  You might disable a driver through
loader variables (or kernel hints, or whatever), but the
driver will still be present in the kernel image, so you
cannot load a module that uses the same symbols.

You will have to compile a kernel that does not include
the driver.

Too bad.  (Why don't you have that option?)

Best regards
