How do I stop games from changing to windowed borderless

For example with RDR2 I have the game settings saved to fullscreen, but sometimes (maybe because of its launcher) this setting changes to windowed, is there a way to force an .exe (for the game) to stay in fullscreen?

Check the "settings" for things like that...

%userprofile%\Documents\Rockstar Games\Red Dead Redemption 2\Settings\

Yes it's already set and saved to fullscreen.

Sometimes when I boot up the game and check the settings notice it has changed to windowed, so I change it back to fullscreen and apply, then after a boot up or two it changes again to windowed and so on.

I also play Battlefield 1, it's set to fullscreen and it never changes to windowed no matter what, not by itself like with RDR2 and not even when I press the Windows key.
