Question How to disable lights per camera in URP? Or prevent Inl_ScriptableRenderer.SetupLights being called?

Hello,

I have 2 cameras in my scene, one camera to display everything in the game, and a second camera to only display dots tracking each game object, which I display to a render texture to act as a radar)

I noticed in the profiler that this radar camera is calling Inl_ScriptableRenderer.SetupLights, and it's taking a lot of time to do so. So it appears that this camera is trying to render lights that it cannot see. I've set culling on the camera so it can only see the dots. I've even set up light layers so that the dots don't get lit up, and I've set them as an Unlit shader, but it doesn't help.
As long as there are lights in the scene Inl_ScriptableRenderer.SetupLights will get called on the camera
In the screenshot below you can see nearly 2ms is being used by this camera calling SetupLights, when then objects it sees aren't being affected by any lights.

I could just use less lights, but I'd still like to know if this is possible, as I use 3 cameras in my game scene and I don't want them spending time on lights they can't see.

Thanks

 

Can anyone at Unity help out with this? Thanks

 

It would be a nice solution that we could use different render pipeline assets per camera to disable so that we can customize settings per camera

But it's scary no one has answered this in so long...
