Outside of games that got unofficially ported to VR [spoiler]and those old TF2 and HL2 VR modes that don't work anymore[/spoiler], nothing actually supports KB+M. I'm not sure why you'd even want to use it in VR anyways when immersion is part of the point.
Just use your VR controllers on their own or buy a stock like the one in your picture if you're willing to live with the drawbacks and have the money to blow.
