How to disable volume control in Volumio 2

Hi to all and to the wonderful Volumio lead developers.

I’m testing the latest release and I see the player had many improvements.

Anyway I didn’t find a way to exclude the volume control knob in Volumio 2 so that I can use only the physical knob of my NAD 319 Amplifier.

I know that probably there is some config file somewhere to be edited and modified…

Could you help?
