Noise when push button is engaged

2020 GLC 300 base -
when the push button is engaged a single click or knock comes from what I think is the instrument panel. No other problems outside of this and it happens every time the button is pushed to start the car, but doesn’t happen when I turn off the car.

update: the steering wheel was trying to adjust higher that the highest setting causing the knock.

Do you mean the "start" button? Or another? Please clarify.
Hope it's nothing.

I think it's the sound of the entertainment system and all the other electronic circuits turning on.
