Are you using the blender rig exporter/importer? Before exporting an animation, there’s options if you scroll a little down for toggling what limbs are in the animation.

After importing animation, scroll down till you see a hierarchy of your motor6d’s. Then, just enable/disable the joints you want to be in the animation or not.
