Is your feature request related to a problem? Please describe.

It isn't related to a problem, just a suggestion for clarity. The UI doesn't show what protocol is assumed for port 853 traffic like it does for 53.

Describe the solution you like

Add port information for 853 as DNS over QUIC/TLS. Perhaps it could be called "DNSoQT".

Describe alternatives you considered

An alias takes up more space in the UI and requires alias-processing.

Additional context

DNS over QUIC (TLS) and TLS is performed over port 853.

There are RFCs for this port for this usage. Not yet IANA, though. (Edit: It's widely used and considered for it, even DNS providers such as Cloudflare and Quad9 use it as such.)
