        if obj.data.bones[bone].name.startswith(ORG_PREFIX):
            obj.data.bones[bone].use_deform = True
        else:
            obj.data.bones[bone].use_deform = False

This is the change in coding, swapping the DEF_PREFIX with ORG_PREFIX , this should give you rig of 75 bones, if you export with “only deform bones” in the fbx
