Hi,
Thanks for using Community Events.
We do not have a feature to hide events in the admin.
It could be possible with a customization.
Following our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
You can move and edit this file in your theme:
the-events-calendar-community-events\views\community\modules\taxonomy.php
There you can modify this function: (get_terms)
$event_cats = get_terms( TribeEvents::TAXONOMY, array( ‘hide_empty’ => false ) );
By adding exclude as outlined in the WordPress Codex:

Let me know if you have any follow up questions.
Thanks
