Control of an object that uses a spline

[_Aka_]

• Disable the spline controller in code - when I try to change the transform position of the object, the spline controller still makes it stay on the path.  Maybe because I'm trying to do the movement in the same frame as when I disable the controller?
  

This one is supposed to work. Maybe you execute the code disabling the spline controller component after said controller run its update method, modifying the transform.
If what I said does not apply on your use case, can you send me a simple reproduction case please?
Thanks, and have a nice
