Deactivate option on Monday form

I am using a Monday form to collect registration information for an event. The form asks the registrant to select a preferred time of arrival to the event. Is it possible to deactivate a time from the list of options so that it can no longer be selected as an option? We have a limit for how many registrations we can have per time slot but it’s not a hard limit nor is it first come first serve so I can’t use logic like “when the 11:00am time slot has 10 registrations deactivate it”.
