Hide chord diagram for certain regions

Let’s say I have a pop tune with 20 times the same chord-progression and I have a guitar-beginner who plays it.
I would like to show him the chord diagram for the first 4 or 8 bars but then hide the diagrams and just let him see the chord name, not the diagram anymore.
So what do I have to do to just show ‘F5 E5 A5’ after a couple of bars and no diagram anymore?
Is the only workaround to create a second instrument?

In properties panel-show only…

sorry, I can’t find it.
Maybe it’s a new feature in Dorico 4.0?
I’m still with 3.5 cause the new update doesn’t work with High Sierra.
I can’t find anything in Write or Engrave mode.
This is my properties panel in Engrave Mode:

Yes, it’s a new feature added in Dorico 4, so you don’t have it in Dorico 3.5, I’m afraid.

ok, thanx Daniel
