Hide items, even if there are items in FullCalendar

Question

I have listMonth as my initialView in FullCalendar.

Here's my FullCalendar js:

calendar = new FullCalendar.Calendar(calendarEl, {
    initialView: 'listMonth',
    themeSystem: 'bootstrap',
    headerToolbar: {
        left: 'prev,next today',
        center: 'title',
        right: 'listMonth',
    },
    locale: 'en',
    timeZone: 'Asia/Almaty',
    height: 800,
    weekends: false

I want to hide items that will appear in weekends
