Unable to enable IPv6 in AdGuardHome v0.107.64 on Raspberry Pi (no UI option)

### The problem

I am running AdGuard Home v0.107.64 on a Raspberry Pi4 and trying to filter DNS traffic from IPv6 clients in my local network.

Current setup:

Raspberry Pi IPv4: 192.168.x.x

Raspberry Pi IPv6: multiple global IPv6 addresses

AdGuard Home listens correctly on IPv4 (:53)

IPv6 clients fail to resolve DNS through AdGuard (dig @ example.com AAAA returns “connection refused”)

Adding IPv6 ("::") to bind_hosts in AdGuardHome.yaml prevents AdGuard from starting with error: cannot unmarshall !! seq into netip.addr

Observations:

IPv4 DNS requests are filtered correctly.

IPv6 requests never reach AdGuard.

Router handles IPv4/IPv6 internally.

Questions:

Is there a supported way in v0.107.64 to allow AdGuard Home to listen on IPv6 addresses?

If not, which version or configuration would enable IPv6 filtering without startup errors?

Thank you!

### Proposed solution

offering an UI configuration option for IPv6
offering a syntax for editing the bind-hosts / AdGuardHome.yaml
