Autofocus on R5 mk2

The R5 mk2 is a superb camera. When things get busy, example, shooting sports where spectators are looking on, I found the facial recognition can be a hindrance. Has anybody experienced a similar scenario, and found a solution that works in the field and is reliable. Assigning a switch to disable is a suggestion. But what is the practical realities of dealing with another button in fast action sports ?
