Vraylight Dome HDRI Override

[jujubee]

I'm using a combination of a HDRI and a low powered VRaysun/sky (for defined shadows) set as a Dome Light in Max.
I'm trying to get rid of the background at certain angles and substitute it with a plain color such as white.
Setting the Dome light to invisible doesn't work.
Removing the HDRI from the environment mapping doesn't work (only in the viewport.)
Adding the HDRI to the Render Setup Environment as an override doesn't work.

Nothing actually seems to work aside from overrides within Vantage and even then I can't get a completely white background if I'm using a custom temperature.
I supposed I could always try to export it out with an alpha background and manually add one in post?

Vantage supports only a single environment map which is imported from one of the Dome lights in the V-Ray scene, or if there are none, from the environment settings ("Environment and Effects" or the V-Ray overrides).
The "background" override options in Vantage are not imported from the V-Ray scene at all.

Is this something that you may plan on implementing? I was going crazy trying to figure out what I was doing wrong...

No immediate plans, but maybe in the future.
Multiple dome lights will surely affect the performance.
