Yes! From your user profile, tap the gear icon at the top right (settings), then select the frequency you want for notifications.
You can also toggle on / off trending room notifications, or choose to pause notifications.
If you feel like you're getting too many notifications, we'd recommend choosing "very infrequently" so you'll still get notified about co-follows, when you get pinged into a room, and when your invitees join.
Notifications are important in Clubhouse since everything is live, and we encourage you to manage them to suit your preferences.
