Direct PHP execution blocked

Hi. I’m using Pagelayer in Cloudways servers and they launched a new feature that blocks direct PHP execution on WordPress as a way to mitigate consequences of attacks, which prevents givejs and givecss from running via nginx (as reverse proxy) firewall rules. Is there a way to force the admin-ajax.php workaround implemented on 1.3.1 so I don’t have to drop that security measure? Thank you.
