Yep. Some folks suggest shifting aim down (to the hips) rather than up (to the head). Hips are larger and don't bob around as much.
I practice both ... I suppose which one to use is one of those quarter-second judgement calls that shouldn't be second-guessed.
Shooting the hips would be done to shatter the supporting bone. You’d better be sure he’s not gonna get to you with one more long step + reach + intent.
