Hide a specific category title from displaying on site

You can use the same code, you just have to find the id of your category by slug.
Yo can do this by adding : 

  $idObj = get_category_by_slug('category-slug'); 
  $id = $idObj->term_id;

And then put $id in your excluding array.
the function is documented here : wordpress documentation
