You can force the layout settings used by the whole site or by a particular page.
Force layout settings across your site
If you want the layout settings to be used throughout your site, add the code snippet to the functions.php file. This would override layout settings across the site.
Force layout settings on specific pages
If you want to replace only the loop on a page, create a template and set the page to use the template.
For example, if I want to replace the loop on my Portfolio page, I create page-portfolio.php and select Portfolio as the template for the page.
