Does this library have functions that can directly perform transformations on 3DGS objects?

I need to load a 3DGS object, then fix the position of my camera, and directly change the position of the 3DGS target. How can this be achieved? I don't want to achieve this by using the inverse transformation to modify the view_mat of the camera, because I have the need to load multiple 3DGS objects, and I need to position them in the appropriate locations.
