Please describe what you're requesting in more detail. AdGuard Home already supports DNS-over-TCP and DNS-over-TLS.

It is a TCP/TLS connection multiplexing lifter

What I know is tls single-wire connection and not connection multiplexing

Such as H2 connection multiplexing

I assume you mean query pipelining, as described in section 6.2.1.1. We'll probably need to modify dnsproxy for that.
