Trouble Reducing SteamVR Plugin Files in Source Control

My team is making a game which requires the SteamVR unity plugin; however, importing the plugin adds over 1500 files to GitHub even when using the basic gitignore provided on Unity’s GitHub page.
This caused a couple of issues with one of my teammates clone of the repo.

Does anybody know of a better gitignore that includes files from the SteamVR unity plugin or just removing some of the unneeded files that are generated by the package?
