The B757 nose wheel steering has a limited input from rudders so it gives you a free hand on taxi to drink your coffee with the left hand on the taxiway. On takeoff once rolling down the runway you transition to rudders for nose wheel steering and maintain it until nose wheel strut is airborne and centers. We can not shut it off. I think it would help to delay rotation. I used it for V1 cuts in the sim and it worked.
