Private Option for Match History

I looked everywhere on the client and settings and in-game settings and found nothing about an option allowing you to make your match history private. I thought that if you have your champions private from the public then why can't you do the same with your match history too? Not sure if anyone else is interested in such an option just that I'd suggest it since I've seen nothing of the sort. An option to keep matches private to certain friends too would be nice.

I'm widely open to any and all discussion!
