Reversing sensors

[Rushy67]

I realise removing the reverse gear "beep" is possible and has been covered in this forum. But is it possible to deactivate the the reverse beeper but STILL keep the lights on and seat belt warning beeps.
The reason behind this, I wish to fit reversing sensors. Do not want to fit a camera as I do not wish to change original stereo unit or have a camera screen either on in in a corner of the dash.
