Yes- by unplugging it from the head's PCB.

or, by plugging in an external one.

Plugging in an external one does NOT disable the internal speaker.

Yes the internal speaker can be muted....you would program one of the unused I/O pins on the accessory connector for rx audio mute [input]and program another for aux control [output] using toggle mode. Then by connecting the two pins that you programmed above, the internal speaker can be muted by pushing the button(P1 - P4) that you programmed for aux control. Pushing the same button again unmutes the rx audio.

That also will mute 1/16 external audio
