Nginx set root path outside /home/nginx

have a script installed that is setup at /home/yunos but is it possible to edit nginx vhost so root path can be read at /home/yunos?
tried alias but to no avail

yeah thats what i thought :/
could i just assign nginx user to be in the same user group as yunos?

otherwise i guess i have to expose a port to proxy off instead :/

location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://localhost:3000;
}
