Yeah, it's annoying. I use Dvorak but some games don't detect that (a lot of respect to those that do detect it because my qwerty typing isn't very efficient anymore, if I do need to type in addition to game input) and it's easier to switch to qwerty than rebind everything, so I don't want to disable it.

Though if you don't use the other languages, you can remove them from your list. Do a search to find it, MS likes to move this option around so I don't know offhand where it is right now, but if you only have one language/layout, the key combo does nothing. You can also change the hotkeys.
