Hi there,
Thanks for emailing support.
We don’t have a filter for this but you could modify the CSS to not display certain categories with a bit of coding.
For now, the easiest way to do it is to hide the options via CSS like so:

Replace the numbers with the id’s of the categories you want to hide. You can find the ID’s if you go to Events > Categories. Hover over the category you wish to hide and on the bottom left of your screen you should see the ID. You can add this to your themes style.css file or the Community plugin’s CSS by making a copy of /wp-content/plugins/the-events-calendar-community-events/resources/tribe-events-community.css and placing in an ‘events/community’ folder within your theme.
I hope that helps!
Thanks,
Brendan
