Question UniversalAdditionalCameraData.SetRenderer does not work with the Scene View Camera

I'm trying to change the Renderer of the Scene View Camera. But Unity ignores changing the renderer index.
It doesn't matter what index I assign to the Scene View Camera. The rendering always happens with an index of zero.
How do I change the render index of the Scene View Camera?

Here is the simplified code for maximum understanding:

Code (CSharp):

1. var sceneViews = SceneView.sceneViews;
2. for (var i = 0; i < sceneViews.Count; i++)
3. {
4.     var sceneView = (SceneView) sceneViews[i];
5.     if (sceneView.camera.TryGetComponent(out UniversalAdditionalCameraData sceneViewCameraData))
6.     {
7.         sceneViewCameraData.SetRenderer(1);
8.     }
9. }
