First post so please be gentle

I have a factory fit tow bar on my 2015 X3 and I used the reverse camera and tow bar zoom to hitch up to my caravan over the weekend.
Is there a way of reversing using the tow bar zoom without also having the audible pdc bleeps? If I switch the pdc off then I also lose the camera view which defeats the object somewhat. I know I can turn the volume down but it is still annoying
Any suggestions?
