Yes, this is what I meant when I said you can force it to be in AWD mode. Saw similar option in another Hi4 based car though I don't remember which was that (probably Tank 300 or 500).
GWM's Hi4 and Hi4-Z setups don't have the rear axle connected to the engine. That's only in the Hi4-T setup where the motor is actually in the transmission itself and the driveshaft connects both axles. That's only for their Off-road and Pickup range though since it compromises on battery space.
The H6 PHEV might have an electronic LSD and TVC unit since the H6GT PHEV had that from what I remember, and the new drivetrain is very similar.
