Not really a thing. I have one bike with 2 x 11 and the rest are 1 x 12 or 1 x 11. The bike with 2 x 11 has a trim function on the front derailleur so I can eliminate the chain rub on the derailleur.
I'm not really sure how you are not aware. Either you can hear the chain rubbing on the front derailleur or there is a distinct noise that the chain makes when more friction is exerted on it.
