Hi.

Not all distribution have systemd-resolved installed by default. E.g. Debian.
However all distributions have nmcli to set DNS.

This is an example of setting the DNS server using nmcli.

nmcli connection modify "<WIFI SSID>" ipv4.dns "<DNS IP 1>,<DNS IP 2>"
nmcli connection modify "<WIFI SSID>" ipv4.ignore-auto-dns "yes"

Also, network needs to be restarted in order to be effective.

nmcli device disconnect <Network Interface>
nmcli device connect <Network Interface>

Note: These aren't the perfect way to implement this change but they demonstrate the point.

I would suggest to change from systemd-resolved to nmcli to maximize portability.
We can also support both backends too, that would be a great idea as well.

Is it possible to use nmcli for DoH or DoT ?

I'm not sure. But what I'm sure is that even installing systemd-resolved and testing it with shecan DNS or others yields me no results.
It instead adds to the existing DNS servers which causes conflict.

I'm not even sure if systemd-resolved can set DoH or DoT.
