But I'm unaware of any production AWD vehicle which allows that as a "hack" to emulate a sort-of locked differential when your hardware is an open differential.
It's probably used as part of computer controlled traction control on some vehicles, but those systems are usually too smart for their own good in off-road and similarly challenging conditions.
For serious or regular off road work, a mechanical locking diff is the way to go. Yes, most electronic systems will completely freak out and stop you going anywhere in soft sand until you remember to turn them off. They do have their place though.
That being said, it’s amazing for snow and ice, but I would not trust it to get me unstuck from rocks or a ditch.
