Not exactly. So if you look at the Team221 Revolution Pro, you'll notice that there is 1 vertical bevel gear that's coaxial with the rotation of the module, and 1 horizontal bevel gear.
Essentially, instead of using just 1 horizontal bevel gear, if you use 2 on opposite sides of the vertical bevel, the vertical bevel gear applies force in two opposite directions and won't cause the module to rotate. Granted, this gives you the issue of having the two horizontal bevel gears rotating in opposite directions so you'd have to cantilever them, but it would guarantee (in theory) that nothing moves when you don't want it to.
