Rendered View - Display only camera view - 2.81

Hi Guys,
I recently started with Blender and it’s great so far but I was wondering if it is possible to see only what camera is seeing in rendered Viewport (eevee)? Currently when I go to camera view the area outside of camera view is darker but is it possible not see it at all?

Increase the opacity of Passepartout to 1 under Camera Properties > Viewport Display:

That’s what I needed. Thank you!
