Rendering to a portion of screen without cutting off anything that was visible during fullscreen

Question

I want to render a camera's rendering only to a part of game screen for which I change some numbers on that camera's viewport. But, because of this I don't see everything that I was able to see when it was full-screen(i.e. without changing anything in camera's viewport). In the attachments below I see whole cube when rendered on full-screen but when I change the viewport to render on top left part of screen, part of the cube is not visible.

Is their a way I can render only to a portion of screen without cutting off anything that was visible during full screen ?

Try rendering the camera into a Render texture and then setting up a UICanvas with a Raw Image in it. Place the Raw Image to cover the exact portion of the screen you want and put your Render Texture there.
