Gate / Trunk to beep or not to beep.

Hi all,

This is my third post with a question (will be the last for now).
So, I have my new FX30d, great car! Happy to have it!

Question about the automatic close rear-door / trunk / gate.
It beeps when you open it. Or, as the manual of Infiniti calls it: a chime.

Does anyone know how to kill the beep when you open/close the ‘gate’ / rear-door / trunk?
