There's no magic UE4 slider that's going to make all UE4 games easy to port to Switch. A UE4 game can be created so that it is impossible to run on PS4 Pro beyond 1 frames per second if you so chose, no matter how you scale it. Example, you have 10 billion characters appear on screen at the same time.
It's not always a matter of scaling graphics. Removing entire assets is another factor, and that usually has to be done and compensated for manually, which is where most of the workload comes in.

Then we have to consider 'fixed' costs like game logic, AI, animation/physics, shadow maps (guess you could lower the shadow map resolution here), geometry and that's not even including platform specific optimizations like AMD GPU vs Nvidia GPU (Maxwell based GPUs like the one in the Switch has no ability to do async compute.) ...
