I've found a way to change to render region mode quickly, in customize i set up a shortcut key to "Edit Region".
Now when i want to change from render view to render region i press my shortcut and render region marquee apears in the viewport.
But i don't know how to change from render region to render view without enter in thr frame buffer.
