NGINX Configuration for Multi-Tenant Application with Domain Mapping

I'm developing a multi-tenant application with Laravel (PHP) as backend; and using NGINX as my web-server.

Aim: To allow each of my tenant to have their own subdomains; and also let them map their own subdomains or root domains using CNAME. Each subdomain / root domain will be served via HTTPS.

My NGINX Configuration -

server {
    listen 80;
    listen [::]:80;
    server_name *.domain.com;
    return 301 https://$host$request_uri;
}

server {
        listen 443 ssl;

        root /var/www/html/public;

        add_header X-Frame-Options "SAMEORIGIN";
        add_header X-XSS-Protection "1; mode=block";
        add_header X-Content-Type-Options "nosniff";

        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

        charset utf-8;

        server_name *.domain.com;

    ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/domain.com/privkey.pem;   

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {
                fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
                fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
                include fastcgi_params;
        }

        location ~ /\.(?!well-known).* {
                deny all;
        }
}

Above configuration works for any <subdomain>.domain.com that my users can create from the web UI of my application.

My aim is to let them point their CNAME records to their respective <subdomain>.domain.com and have a complete white-label solution that runs on their own domain.

Would really appreciate some guidance.
