Update skeleton at fixed rate for physics/gameplay but every frame for rendering

hi, is it possible to animate a skeleton without a mesh attached to it to a specific framerate no matter what the actual framerate is, so that gameplay related stuff on it (ie hitboxes) work consistently, while also having another skeleton copy that skeleton but at the actual rendering framerate?
I’m making a melee combat game so I want all the gameplay stuff tied to skeletons to work properly but without the rendering side of the animations being affected
