How to setup unauthenticated paths inside an authenticated reverse proxy service?

Describe the problem

I have a self hosted application (silverbullet.md) that does not support authentication on some paths ( Authentication Proxy ). Right now, my setup uses reverse proxy with a subdomain and the service is set with authentication (I don’t want to have this open to everybody). However, things failed since a few paths cannot be authenticated.

In summary, what I need is:

myhost.mydomain.com -> silverbullet.lan:3000 (Authenticated) this is OK
myhost.mydomain.com -> silverbullet.lan:3000/service_worker.js (Unauthenticated).

I tried creating a different service (with a path, instead of a resource inside the main authenticated service) but netbird won’t allow me to since the subdomain is the same.

Is this at all possible ?
