Nginx переадресация с директории на поддомен?

Так, вот мой конфиг, полагаю, это говнокод, но оно работает, и поэтому вдруг кому пригодится

server {

    server_name example www.example;

    location / {
        root /var/www/example;
        index index.html index.htm ;
        try_files $uri $uri/ /dir/index.html =404;
    }

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

server {
    server_name *.example;
    root /var/www/example/ddd/$1;
    index index.html index.htm ;

    location / {

        try_files $uri $uri/ /ddd/index.html =404;
    }

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example-0001/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example-0001/privkey.pem; # managed by Certbot

}

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

    listen 80;
    listen [::]:80;
    server_name example www.example;
    return 404; # managed by Certbot

}
