Want to https://www.example.org to https://example.org in Nginx

I want to redirect https://www.example.com to https://example.com in Nginx.

I tried to do this using with below code, but I have to redirect multiple domains so can't mention specific "example.com" in the return line. I have around 30 different domains for which this need to be done.

I have gone through many suggested solutions but all are with one domain which doesn't meet my requirement. Like if there are domains (example.com,example.com,xyz.com etc) all need to redirect to https://respectivedomain(non-www)

server {
    listen 443 ssl http2;
    server_name www.example.com;

    # redirects www to non-www. wasn't work for me without this server block
    return 301 $scheme://example.com$request_uri;
}
