      Well some EV models do have free wheeling clutches. However that usually works with just two pedals. If you press neither “give me torque” (accelerator) or “give me negative torque” (brake), ECU orders a free wheeling clutch automatically open to remove the drag of spinning around the electric motor rotor. Atleast some Porches do this with their front axle on AWD cars for efficiency.

      I guess nothing really would prevent doing it on main axle or both axles on AWD, except maybe reaction time. It takes that couple milliseconds for actuator to close the clutch/let the clutch close on biased closed system.
