Override HDRI backdrop?

[DanSHP]

IS there a way to have one HDRI lighting my scene and another standalone for the background/sky? I'd like to be able to control/manipulate each independently. What is the correct setup to do this?

For example, reduce the exposure of the background sky and alter the hue without affecting the direct lighting in my scene.

Another point does GPU support environment overrides specifically, the reflection one? I cant seem to get it working.

one invisible

1 with default settings

1 "affect diffuse/specular/reflections" turned off

No problem on a simple scene. Note that the overrides affect the 3ds Max environment settings only.
