How to configure nginx to redirect to without www on all subdomains?

Question

Nginx

There is an example.com domain that has custom subdomains *.example.com.
How to write a redirect in nginx config so that www.*.example.com addresses become *.example.com?
If from www.example.com to example.com then everything is simple.
server {
server_name www.example.com;
rewrite ^/(.*)$ example.com/$1;
}
And here with subdomains so does not work any more.

server {
    server_name  www.*.example.com;
    rewrite ^/(.*)$ http://*.example.com/$1;
}

In general, the answer was this.

server {
    server_name ~^(www\.)(?<domain>.+)$;
    return 301 $scheme://$domain$request_uri;
}

server {
    listen 80 default_server;
    listen [::]:80;
    server_name ~^(www\.)(?<domain>.+)$;
}

Answer 1

server {
    server_name ~^(www\.)(?<domain>.+)$;
    return 301 $scheme://$domain$request_uri;
}

server {
    listen 80 default_server;
    listen [::]:80;
    server_name ~^(www\.)?(?<domain>.+)$;
}

Answer 2

server {
server_name ~^(?!www\.);
return 301 $scheme://$host$request_uri;
}
