No need to unplug. You can also disable FF in one of the .lua files but forgot which one.
Btw, FF wheel makes a great collective if you do not have HOTAS, just joystick. Just set forces to zero for BS in wheel config software. I actually use my Logitech MOMO wheel as throttle in every sim I have (except in Condor sailplanes where I use it as elevator trim) :)
