Allow only existing Clients for DoH, is it possible?

[ghostersk]

I just found out that I can specify unique identifier for DNS over HTTPS, by adding some client name after dns-query
I was long time strugling to identify what device is making the query.

The question I have is if I can block all HTTPS queries if the client does not exist?
Maybe if it is domain.com/dns-query too
And allowed existing queries like domain.com/dns-query/existing-client

Edit:
I just noticed this in the DNS section, however I am not sure if this is what I want to use.
As I want to block all non existing clients on DNS over HTTPS, but i do not want to touch any dns provided by #53 port.
As I am using Traefik proxy in docker, it hiding the ip of real client behind the proxy or container ip if I am using normal dns from wireguard network.

I would like to apply this client filter only for DNS over HTTPS

There's only one set of Access settings for all protocols, so you cannot currently prohibit access for a set of ClientIDs only on one protocol.
