DoT (DNS-over-TLS) or DoH (DNS-over-HTTP) support
I just recently learned that NetworkManager has a per-profile option for DNS-over-TLS. It would be nice if a toggle for this could be exposed.
I'm not entirely sure if this can be supported without systemd-resolved though. See https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/aaaf727b97d8ce1a89a76d9e13808dffa7e3ecf3/src/libnm-core-impl/nm-setting-connection.c#L2539-2573
