Can I hide apps in Nova Launcher's drawer?
There's an option to hide apps in Nova Settings > App drawer > Hide apps.
You can also long press an app icon in the app drawer and click the icon that looks like an eye.
Keep in mind, however, that this is meant to be an organizational tool and not a way to globally hide apps. Any hidden apps will still show up on the home screen and in search. If you want to completely hide an app, you'll need to use a third-party tool as this isn't something Nova Launcher can do.
