Allow Schedule Updates? controls whether attendees can change their own session schedule after completing registration. Leave it on if attendees should be able to add more sessions later from their schedule or session pages. Turn it off to keep their choices fixed.
Open Event Settings > Event Experience > Registration & Checkout.
Under Can Attendees Build Their Own Schedule?, switch Allow Schedule Updates? off.
Select Save.
What attendees can still do
Attendees can still access sessions permitted by their tickets. Turning off schedule updates hides their self-service options for adding or managing sessions after registration. Event team members can still manage attendee records from the dashboard.
Keep the checkout step separate
This setting controls changes after registration. If attendees should choose sessions during checkout, keep Can Attendees Build Their Own Schedule? configured for that flow, then use Allow Schedule Updates? to decide whether they can change those choices later.
