You can customize the Networking Hub experience by configuring the settings within your Admin Dashboard. Event organizers can disable random user mingle within a Networking Hub. To do so, follow these steps:
Log in to your Admin Dashboard
Select Edit next to the Networking Hub
Scroll down to the Networking Hub Settings
With just a toggle of a switch - you can hide random user mingle amongst all of your attendees within a Networking Hub. There is not a current option to disable random Circle mingle as it is encouraged for your attendees to go in and out of a Circle as they please.
