The following games have VR support :
- Zelda: breath of the Wild
- Captain Toad: Treasure Tracker
- Super Mario Odyssey
- Super Smash Bros.
- Spice & Wolf VR
- Labo VR
Just consider it fun to play these games in VR mode but the Switch screen doesn't have a resolution as high as the Oculus headsets so don't expect some awesome VR experience.
You can get a a Chinese VR headset for the Switch for $20~$30.
That is already a high price if you ask me.
Maybe try to get a secondhand Labo VR set for a few bucks on eBay to try it out.
