DIsable rear parking sensors using OBD11?

[Howzat]

Just wondering if it's possible with OBD11 and if anyone can remenber where the setting might be?
Minor ding on the rear bumper has popped a sensor off so I've unplugged it until the bumper is fixed but I get this really loud and annoying beep in the cab every time I go into reverse.

Would turning volume off suffice?
Can be done in adapatations - separate settings for front and rear.

Not entirely sure but I think volumes do not affect the fault beep - at least I had some issues at some point and the fault is always at full blast.

Probably even removing the PDC module from gateway installation list would not stop it from working.

I may be wrong but I think unplugging the PDC module from under the dash would be the easiest fix
