Yes:

        location ~ ^(.*)/$ {
                # matches directories
-               set $path index.htm;
+               fastcgi_index index.htm;
-               fastcgi_param QUERY_STRING f=$request_uri$path;
+               fastcgi_param QUERY_STRING f=$fastcgi_script_name$is_args$args;
                fastcgi_param DOCUMENT_ROOT $document_root;
                fastcgi_param SCRIPT_FILENAME /var/www/builder/parser.php;
                fastcgi_pass 127.0.0.1:9000;
        }
