There’s no way around it unless the engine moves with the suspension
Yes, there is.
Take a conventional front engine, rear wheel drive drivetrain. Rotate the drive train 90 degrees about the rear axle, as if the automobile has its nose in the air, with the driveshaft oriented vertically.
You can steer the vehicle by rotating the entire axle around the axis of the driveshaft, though it isn’t perfect or space efficient, it would require no universal or CV joints. It would behave sort of like a vehicle with an articulated frame.
The axle could be fixed vertically with uni wheels at the ends of the halfshafts allowing the wheels to travel vertically independent from the axle.
Suspension movement still requires flex in the shaft. There’s no way around it unless the engine moves with the suspension
