Trouble Formatting Nginx Server Block

So I'm trying to set it up where my subdomain: "forum.project-freedom.net" visits the directory of /var/www/forum/ on my server. I'd like the main URL, "project-freedom.net" to be sat on the /var/www/html/ directory of my server. I'm utilizing nginx and here's my current conf file:

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name project-freedom.net www.project-freedom.net;

    ssl_certificate /etc/ssl/certs/1546559737repl_1.crt;
    ssl_certificate_key /etc/ssl/private/project-freedom.key;

    root /var/www/html;
    index index.html index.htm index.nginx-debian.html;

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

    location /forum {
        alias /var/www/forum;
        index index.php index.html index.htm;

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock; # Change to match your PHP version
        }
    }

    # Redirect non-www to www
    if ($host = 'project-freedom.net') {
        return 301 https://www.project-freedom.net$request_uri;
    }

    # Redirect HTTP to HTTPS
    if ($scheme != "https") {
        return 301 https://$server_name$request_uri;
    }
}

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name forum.project-freedom.net;

    ssl_certificate /etc/ssl/certs/1546559737repl_1.crt;
    ssl_certificate_key /etc/ssl/private/project-freedom.key;

    root /var/www/forum;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock; # Change to match your PHP version
    }

    # Redirect HTTP to HTTPS
    if ($scheme != "https") {
        return 301 https://$server_name$request_uri;
    }
}
