Disable booking on specific dates

Problem/Motivation

I created a monthly calendar with Bookable Calendar and Calendar View combining two different Calendar Openings and everything seems to work very well. However, I would like to disable the bookings on certain dates like Christmas, Easter, national and local holidays, vacations, and so on. I did some research but couldn't find an answer, so I'm asking here. Is there a way to do this with Bookable Calendar? Thanks.
