You can reduce server load by configuring nginx to not cache certain web
content (for example, dynamic content that is not viewed often). To do
so, specify the desired
$request_uri
in the “Disable caching for locations” field. For example, if you
specify /wp-admin/,
nginx will not cache content related to
WordPress Admin Panel.

Note: If you want to specify several values in the “Cache requests with
cookies“ and “Disable caching for locations“ fields, specify each one
on a separate line.
