Heirlooms. Can I turn them "off"?

Just incase I unlock one in the near future; I want to know if it's possible to "unequip" them from the 'Legends' tab (pre-game). Me personally, I like having the screen clear, and I already like the Legends standard idle animations. I also like cracking my knuckles pretty often -always a crowdpleaser after scoring big. 

I can't seem to find some pictures of any tabs that get unlocked or what have you.
