Any type of meta data (or anything else, for that matter) can be turned off with CSS.
1. Edit the theme that displays post(s) in question.
2. Edit the Void Post Grid widget.
3. Click on the Advanced tab.
4. At the bottom click on CSS.
5. Add the CSS below, setting the class or classes for the meta you want to hide.
6. In the example below the updated on date, the links to any tags associated with the post and the link to enter a comment are hidden.
Hope this helps
