Yeah just need larger motors that can put out more torque which adds more cost and weight. Or you can have a way to connect each side with a locker or a single larger motor with brake locker control like dual motor vs quad motor Rivian's. Again the quad motor Rivian can be stalled on rock crawling due to lack of torque when multiple wheels lose traction.
Electric motors have a lot of torque but EV drive trains are usually single speed so it must not have too much gear reduction for highway speed. A modern ICE offroad vehicle has a multispeed transmission with torque converter that greatly amplifies stall torque along with a transfer case that has a low range that multiplies even further. I would imagine when jeep does an electric production Wrangler it will probably have dual motors with lockers and may even have a 2 speed transmission for low range. Maybe they will even do like their Magento prototype and run a single large electric motor through a traditional transfer case and driveline.
