Hello,
I am trying to disable gzip to mitigate the breach attack( I use a service to check for vulnerabilities and it came up with that). I added gzip off to nginx.conf file and then check the configuration with nginx -t, and then reloaded with systemctl reload nginx.

When I visit the site, I still have
Accept-Encoding: gzip, deflate, br

I check that I dont have gip on anywhere else on /etc/nginx/*
grep -Ri "gzip off" /etc/nginx

I also use brave in incognito mode to make sure there was no cache involve.

Not sure what else to do to disable gzip

I am running php 8.1, nginx1.24 on ubuntu (22.04.03)

this is the result of nginx -V
nginx version: nginx/1.24.0
