eventInteractive
Setting to true will cause all events to be focusable/tabbable. Setting to false makes them non-interactive (except events with a url).
Boolean, default: unset
When set, this calendar-wide option wins. When left unset, each event’s own interactive boolean of the event object decides. When that is also unset, events are interactive if an eventClick handler is defined.
Events with a url always render as links and are always interactive, regardless of these settings.
