Is it possible to hide z-block on a sub-category page?

I have one z-block running on all my web-site pages. Is it possible to hide it on a particular sub-category page?

 

It is possible to show z-blocks in subcategories and then choose categories where you want the block to be displayed. You can do it from the Categories Tab in the block settings.
