[Defender Pro] Prevent Information Disclosure

With the last update on Defender, now appears a new SECURITY TWEAKS: Prevent Information Disclosure
The recommendation is:
Copy the generated code into your site specific .conf file usually located in a subdirectory under /etc/nginx/… or /usr/local/nginx/conf/…
But I don’t have acces to these directories, so how could I resolve the issue?
Thanks.
