But the aim to switch 2 ADRs OFF is just exactly what is requested from a crew to deactivate a mad protection, with the associated risk to turn off 2 IRs instead ... Not easy to locate the proper switches on the overhead panel in the middle of such critical situation.
What about a single red guarded switch in the middle of the dash to give back control to the crew ... ?
