I can't verify this.
If I turn on the option "play chords through midi", I can change the volume of the strumming in the mixer with the fader of the thru channel from max to zero.
But what for? The strumming is a simplified pattern and should only give you a hint what the chord sounds like and makes no fun to listen to.
The guitar tutor in my opinion is at first an optical representation of the chords being played, so you can learn the chords of the song in an easy way.
RTFM: "Enable Chord Tutor Display: This setting silently displays the chords on the guitar fretboard."
Maybe you can explain how you wanna use it.
