I know I'm very late to the party but if you uninstall an app there is a option on the left hand side to view apps 'on my device'. All the steam vr games and apps are there permanently but as for infinity games and purchased Viveport tiles you can effectively hide them by uninstalling.
How do I remove a app from my library (even uninstall will do)
in VIVE & VIVE Pro
