Notes

DNS port 53 is available for AdGuard Home because the systemd-resolved DNS stub listener has been disabled.
/etc/systemd/resolved.conf.d/adguardhome.conf configures systemd-resolved to use AdGuard Home at 127.0.0.1 with the DNS stub listener disabled, allowing AdGuard Home to use port 53.
The server itself continues to use AdGuard Home at 127.0.0.1 for DNS resolution.
The original /etc/resolv.conf is backed up at /etc/resolv.conf.backup.
/etc/resolv.conf is linked to /run/systemd/resolve/resolv.conf, allowing systemd-resolved to use the configured DNS server without occupying port 53.
