How to Limit FPS of VR Scene Capture?

My VR project has a separate spectator view on the monitor that is rendered from a scene capture camera. It is currently functional, but it lowers the framerate significantly. I need to have the scene capture run at a capped 30 FPS (for example) instead of at each frame the VR headset outputs.

You can see there is an option to disable capturing every frame. When hovering over the option it advises to capture manually from blueprints if you disable this.

I just started using blueprints a few days ago so I am not sure how to approach this. I would appreciate if someone could give me a pointer as to how I would go about doing this.

One way of doing is to Set a timer for event with the desired period (for 30fps, 0.333… ms) and execute the capture there.
