What do you mean by "owned"?  If there's no dhclient running and an
interface configured for dhcp associates or negotiates a link, devd
starts a dhclient.  Assuming I get time to make the necessicary changes
and push the issue, netif won't start dhclient at all in the future.

I wouldn't recommend it unless you never lose association since if you do and
you remove the lines in devd.conf you will end up without a dhclient.
