My 2020 DCT does this as well. its an audible click similar to the click when you pull in the front brake lever. it will also do it if i accelerate a little, hold then twist the throttle a little more, and then again if i pull more etc.
I have also noticed it does the click when i downshift manually with the "paddles" even with no hand on the throttle.
It does bother me as i am a bit OCD (not crazy ritual OCD mind you) but its annoying as i can hear it even with shield down.
