disable 2e screen at startup

[robocopys]

Is there a way to disable the 2e screen at startup, so I don't need to disable it every time myself. Because when I don't do that some windows 'disappear' in the 'black' second screen,not being accessible but after disabling the 2e screen.
So is there a way to disable the 2e screen at startup, by Applescript I can't manage to do it,because the Mac doesn't recognise a third party submenu in the menubar in the top right corner .

I want this one too.

I know this can be done with command line interface, but I am kind of lazy to find how to use launchd to make it work. Any idea ?
