Sorry I did not read every post in this one but there is a nose Wheel Steering control one can assign to a twist handle of joystick.
However, the way the tiller is done is that it’s not assigned to a single axis like a rudder but to an input if I remember well.
That means the nose wheel does not automatically center when you release pressure/input on the axis. You need to do this manually by going the opposite direction.
When I felt that this is not easy to control, I disabled it back then and back to rudder for both.
