To set a guest as inactive, open your connected Person Form and update their entry. If your form includes an Is Active? field, change this value to No for the guest you want to deactivate.
If you want to deactivate an entire guest list, you can also deselect the corresponding Person Form in the Allowed Guest Types settings.
Keep in mind that even if a guest is inactive or removed from a list, they can still log in if they’ve been sent an authenticated Save & Resume or Workflow link and there’s a Public role view available for that form. To fully restrict access, make sure no authenticated links or Public views remain available to them.
