If you don't want to hardcode the domain name, you can use this redirect block. The domain without the leading www is saved as variable $domain which can be reused in the redirect statement.

server {

    # Redirect www to non-www
    if ( $host ~ ^www\.(?.+) ) {
       rewrite ^/(.*)$ $scheme://$domain/$1;
    }
}
