How to re-create this built-in RP setup with URP?

In the built-in RP, I create 1 scene per menu/screen. i.e. 1 scene for the end-game screen, 1 scene for pause menu, 1 scene for game scene, 1 scene for main menu, etc. Each scene has its own camera to render what it needs and I just set the camera depth, clear flags, & culling mask to only show the UI.

In URP, the camera has had a big overhaul and I'm not sure how to do this. The way to do it seems to be with camera stacking, but my cameras are different scenes so they can't have a reference to any 1 camera.
