I have a network WIFI interface that will be always in monitor mode, but I suspect the DHCP client is trying to set it up and I do see the following errors on my logs (journalctl) constanstly:

There is a way to tell the DHCP client to ignore this interface completely?

Not sure what to try to disable this error, I don’t see any options for /etc/wpa_supplicant/wpa_supplicant.conf (man wpa_supplicant.conf).

Thanks,
Jose
