How to use a folder out of Grav CMS control

Hi all,

I need to use a url like https://mydomain.com/othercomplexthing linked to another folder in the same domain and server where the Grav CMS installation is.

I know that the folder need to be hard-linked, but i dont know how to configure grav to put this folder out of his manage.

I have configured Multisite with folder estructure, but the folder added is under Grav CMS mange.

Any sugestion or help.

I have done it by nginx configuration adding this to my domain conf file
location /othercomplexthing {
alias /var/www/othercomplexthing;
index index.php index.html index.htm;
}

I think can be better doing with grav CMS setup, any idea to do it with grav CMS config
