Disabling an audio alarm that might cover other alarms or communication in the cockpit makes sense, but not the shaker.
I'd have to disagree there. I had an unusual pitot heat failure mode a bit more than a decade ago on an NG. The stick shaker and overspeed warning were triggered simultaneously along with a plethora of master cautions. While we figured out pretty quickly it was unreliable airspeed, communication in the flightdeck became very difficult and stressful. The overspeed stopped but the stick shaker continued until touchdown and it's a noisy bit of kit.
