UFC is only a competitive sport, and there are many rules and restrictions. For example, only one-on-one and no weapons can be used. You can't make holes, pinch your throat, pick your crotch, turn your joints, grind your teeth, etc. And you can use anything in unrestricted fighting.

Of course, acupuncture can be used, but the key parts will still be limited. If acupuncture is really practiced now, it will stir the world.
