Prevent the .git directory from being server by NGINX

I'm trying to prevent nginx from serving the .git directory. I've tried a number of suggested things from this site, e.g:

    location ~ /\.(?!well-known).* {
             deny all;
             access_log off;
             log_not_found off;
    }
    location ~ /\.(.*)/?(.*)? {
             deny all;
             return 404;
    }

   location ~ /\.git {
            deny all;
    }

But all of these still allow nginx to serve the config file within the .git directory. A https request to server-name/.git/config is still successful.

The output of nginx -T:

 server {
     server_name umami.server-name.ch;

    location / {
            proxy_pass http://localhost:3000;
            proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
