How to make the whole screen when you expand? (Kingdom Come: Deliverance)

Often have to fold, and the game when expand always open in the window. You can of course every time I open the Alt+enter, but then it will be in a window without frames. I would like the entire screen, and therefore always need to go into the settings and set. Is there any way something like, for example by using some sort of team system.cfg, make it so, that the game was unfolding on the entire screen?
