How can I bake URP reflection probes at higher resolutions than 2048?

I’m using reflection probes to create custom skyboxes but the max cubemap capture resolution is 2048. Is there a way to bake at 4096 or even 8192?

I don’t think it’s possible out of the box. You may be able to use Unity - Scripting API: Camera.RenderToCubemap to make a custom script that does it.
