Как настроить nginx только для нескольких запросов?

listen 80;
listen [::]:80;
server_name     surf.site.biz;
	
access_log      off;
error_log       /var/log/nginx/error.surf.log;
	
root            /var/www/html/public;
index           index.php;
	
location /surfing {
        try_files   $uri $uri/ /index.php?$query_string;
}
	
location / {
	deny all;
}

if (!-d $request_filename) {
        rewrite     ^/(.+)/$ /$1 permanent;
}

location ~* \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}

location /surfing {
        try_files   $uri $uri/ @php;
}

location / {
  deny all;
}

location @php {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_param  SCRIPT_FILENAME  $document_root/index.php;
}
