Of course, if you can't move the front der a smidgen and eliminate the noise you get from changing rear cogs.... then what I've just told you is useless and your shop needs to give you a hand.

But maybe it would be useful for someone else.
I have trigger shifters - and someone has explained how to trim it - though it is only available to me if I have shifted up from the granny chain (per my LBS). I will try your experiment this afternoon. I tried to trim yesterday with the smidgen click on the shifter - but little seemed to help when I was in the middle chain. That does not mean that I was trimming it correctly...
