Disable virtual keyboard

I have a dock and was trying to play dota 2 but the virtual keyboard likes to help by popping up randomly and hikacking my cursor for more fun.

I kinda got it to stop doing it by launching the game from desktop mode but i think it's still trying because i get a micro stutter when i close a keyed thing, like type some chat and press enter for example. It's playable but mildly annoying.

Anyone know a way to disable the virtual keyboard? My searching only pulls up posts from about a year ago with negative responses.
