Afaik the Nginx header is hardcoded, so to remove it you have either to change the source/recompile or run through a proxy which can remove http headers.

For the php header you have to change php.ini and set: expose_php = Off

For Drupal there are several modules/plugins which let you remove the header (for example https://www.drupal.org/project/remove_http_headers )
