TUI Calendar - Preventing Overlapping Schedules

Question

I'm using TUI Calendar as a scheduler and all works as expected up until trying to prevent schedules from overlapping. There doesn't seem to be a config item for this like on FullCalendar which uses slotEventOverlap: false,.

I was wondering if anyone has come into this problem and has resolved it another way as I don't think TUI Calendar has a similar config item?

I have tried using the beforeCreateSchedule event to compare against other schedule items but can't seem to gain access to the other schedules on the calendar.
