For all Joomla 3+ templates built using the Zen Grid Framework v4 (any theme after October 2014) please refer to the Zen Grid Framework v4 documentation.
Zen Grid Framework compatible templates have the ability to hide or display the main content on the frontpage of your site. We use this alot when we want to create home pages that use a combination of modules and no content.
In order to hide the main content area on the front page of your site simply navigate to your Joomla administration and in the template settings navigate to Layout –> Settings.
Select: Hide main content / component area on the front page? -> YES.
