How to set up a redirect from www to without www?

Question

Nginx

Good day to all, I read a lot of manuals on Google, but none of them work, I hope for your help) I
installed an ssl certificate for nginx via ppa: python-certbot-nginx, after installation and automatic configuration, the config became like this.
Now there is a redirect from http to https, but how to make it redirect from www to https without www, no idea, no matter how I abuse the config, it doesn’t want to work :C

/etc/nginx/sites-available/site.ru

The server is on DigitalOcean

server {
         listen 443 ssl;
 
        root /var/www/SonyTwo;
        ssl_certificate /etc/letsencrypt/live/site.ru/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/site.ru/privkey.pem; # managed by Certbot
        ssl_dhparam /etc/nginx/dhparam.pem;

        index index.html index.htm index.nginx-debian.html;

        server_name site.ru; 

        location / {
                try_files $uri $uri/ =404;
        }
}

server {
   if ($host = www.site.ru) {
       return 301 https://$host$request_uri;
    }
    if ($host = site.ru) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

        listen 80;
        listen [::]:80;

    server_name site.ru;
    return 405; # managed by Certbot
}

Thank you in advance for your answer
PS Only html files on the server, php is not installed.

It is better not to use if constructs. For your case:
server {
server_name www.site.ru;
listen 80 ;
return 301 https://$host$request_uri;
}
