Until yesterday /etc/resolv.conf was managed by systemd-resolved and I tried the approach to ignore DNS settings from DHCP but no success.
I tried setting ipv4.dns-search to empty via nmcli but /etc/resolv.conf still had the search stanza.
Does anyone know if dhcp-client is renamed or something ?

If you are using NetworkManager then I think you want to set the connection
to "Automatic (addresses only)" then set DNS options manually.
I think that is the nmcli property ipv4.ignore-auto-dns.
If you are using systemd-resolved then you can settings in your
/etc/systemd/network/XXX.newtwork file to ignore settings from DHCP as well
according to the man systemd.network page, See DNS= and Domains=.
