Nope. It's there for a reason, because of the aircrafts divergent nature in pitch, above the AoA limit the aircraft departs from controlled flight and rather enjoys flying backwards.
Manual pitch override is for getting the aircraft out of the deep stall/falling leaf/flat spin that usually follows once you somehow overcome the AoA limiter. You have to hold the MPO switch on and then rock the nose up and down like a swing in order to get it back under the AoA limit and get it flying again.
