The links I've provided explain why you shouldn't do this. In
particular, because this has nothing to do with security, and
because it is an easy way to say "thanks" to the developers,
including me.

Trying to hide "nginx" everywhere, including response headers and
error pages, will at least require 3rd party modules to do so, as
well as non-trivial and error prone error_page configuration. I
would not recommend doing this.

If you insist on not saying "thanks", the most simple available
option is to use 'server_tokens "";' as recommended by the
previous message (and available in the commercial version).
