Hello, sorry but here aren't any settings to do what you are asking.
I think they're obnoxious. I can see why you would want to make them smaller or remove them altogether.
There is a feedback option. You could tell them what you think of it. I'm not sure how truly receptive they are to constructive criticism but if enough people complain, they may add the option. Click on the option wheel at the top right and select "feedback" at the bottom.
