Prime GO record mic input

I know there is an option in the Prime GO to send the mic signal to booth (or to disable the mic signal to booth, to prevent possible feedback). I also know that in the past, the mic signal was not sent to the “Record” signal until firmware 1.5.1, which added the ability to record mic input.

Now my question is: Can I enable/disable the recording of the mic signal? Am I forced to record it?
