You … might want to actually look into using GShade.

You can even turn off all the effects if you don’t like the effects, and simply set a keybind for screenshots and it’ll go into whatever folder you choose. This way you can save screenshots without worrying about Win10 being dumb.

It doesn’t hook into the game or anything - it kinda sits on top if that makes sense? Does not interact with any of the game files, and Squeenix literally does not care if you use it.
