Linux currently doesn’t have a concept of “exclusive fullscreen” in the way that Windows does. A new wayland protocol can probably resolve this, although I’m not sure if any work has been done for that yet.

You could do it manually though most likely by having a script check if the current window is fullscreen (which you can do with sway/wlroots easily at least) and then apply the change. But there would be some false positives where you might not want the behaviour (like a video player), although if you’re watching high resolution/high framerate content it would be useful.
