When I was way ahead in school the solution they came up with was to have me basically be a TA. I memorably almost blew up the chemistry lab as a sophomore (and almost lost my hearing in one ear) due to an over-enthusiastic water hydrolization demo.
That worked for 9-10th grade or so but then I just left and went to college. I spent the earlier school years not in school for elementary, and writing computer code in a notebook in middle school instead of listening to the teacher. So putting me in charge of a bit of the teaching was great and got me more engaged (and social) with other kids.
I've implemented something similar in both academic and non-academic (ski racing) settings with younger (kindergarten/early elementary) kids and for some kids it works great to have a little bit of responsibility for helping out others and teaching.

It's interesting you mention this--I had a similar experience in "computer science" class. (BASIC programming) I and two of my friends were quite disruptive. The wise teacher (who he taught math to my Dad) understood that we not only knew all the material, we knew more than he did. So we were excused to the computer lab for all lectures, and helped out the other students when they got stuck. It was a very productive, win-win solution.
