Hello @jrodriguez88,
The theme already has the option to manage the page layout or the entire layout of the site. If you do not want to display the sidebar in the pages then you can set the option of no sidebar.
For this you can go to Admin Panel > Appearance > Customize > Theme Options > Layout and manage the settings as per your requirement.
For pages, you can even manage the layout setting from the meta-option available in the individual page.
