Pfsense DNS Pro/Argo KB?

Can someone point me to any known knowledge base articles for what Cloudflare supports with DNS Pro + Argo? I don’t want to subscribe unless it’s supported. I imagine I will need to enable DNS Forwarding with the DNS Resolver but if there is some type of authentication that is needed, I wouldnt know how or where to do that in pfSense as there’s no place to enter anything besides a DNS ip / hostname / gateway.

I don’t really understand your question. What you want to do with pfSense?

I was hoping to use the DNS performance routing for general network browsing but it seems the service whether it be DNS Pro or Argo are suited for website specific use cases and no generalized browsing.
