How can I close Unity's Auto Save feature for Screen Size and Fullscreen Mode

I'm writing a detailed settings panel for my game. Everything works fine except screen size and fullscreen mode.

In my settings panel, you have to click "Save Settings" button for saving the settings. I also made that you don't need to click "Save Settings" for seeing that settings effect on game.

So when user change resolution or fullscreen-window mode, Unity saves that. But I don't want to do this. I want to save it when you press it. How can I close Unity's that feature on my game?
