Is it possible to have a camera to only render in capture?


Hi everyone, I would like to create a lens that would only show the effects from a camera in capture. I have done the opposite in the past where the UI is shown live but not in capture but what I'd like to do now is to have the 3D models only shown in capture.

I had the default camera set to Render Target and the Camera with the effects set to Render Target 2, edited the scene config so it reflected what I wanted but the effects still show in both capture and live target.

Does anyone have a clue on what I am doing wrong here? Thanks in advance for your help!!
