Why doesn't 404 work in DLE?

Question

PHP

Lord, I'm afraid of the second day. The task of transferring a site to DLE from Apache to a bunch of NGINX + PHP-FPM is haunting.
Actually, everything took off except for the 404 error for urls that end in ".php", everything else works out perfectly. The Nginx config twisted in every way, it seems that the engine ignores it in this regard. Where can I add a drop so that for ".php" it also worked out a 404 error?
