NGINX How to redirect request to PHP-FPM if *.png is not found?

Question

PHP

Tell me how to redirect a request to PHP-FPM in Nginx if a file with *.png extension is not found? At me the file is generated "on the fly" by a script. NGINX does not skip such a request and returns a 404 response. I need the URL to end with *.png extension.
