remove element from Full calendar

I have a full calendar that allows me to use the events in other elements outside the calendar, however, I would like the default events that come in the calendar such as prev, next, and today to be removed from the calendar so that I you can use their respective functionality in the following elements taskElementPrev, taskElementNext, taskElementToday.

Note: Below a photo with calendar buttons that should be deleted from the calendar pane.

So, in the eventClick I have this function:

  $('#calendar').fullCalendar({
            header: {
                left: 'prev,next today',
                right: 'month,agendaWeek'
            },
            defaultView: 'month',
            viewRender: function (view) {
                var title = view.title;
                $(".taskElementCalendar").html(title);
                var prev = view.prev;
                $(".taskElementPrev").html(prev);
                var next = view.next;
                $(".taskElementPrev").html(next);
                var today = view.today;
                $(".taskElementPrev").html(today);
            }});
