Systemd warnings re: iscsi.service iscsid.socket dependencies

RHEL 7.3 x86_64, fully updated. In logs, every 30-90 seconds:

Jun 29 09:33:03 d3dell systemd: Cannot add dependency job for unit iscsi.service, ignoring: Unit not found.
Jun 29 09:33:03 d3dell systemd: Cannot add dependency job for unit iscsid.socket, ignoring: Unit not found.

I know this is just a warning, but it's annoying, as the system has no iscsi controllers/disks. It seems to be coming from the "Wants:" lists here:

#systemd-analyze dot | grep iscsi
    "sockets.target"->"iscsid.socket" [color="grey66"];
    "sysinit.target"->"iscsi.service" [color="grey66"];

I don't just want to blindly edit systemd config files to eliminate this depdendency, even though it's just a "Wants:". ( I know I can use use a +3 battle axe and do "systemctl mask iscsi.service", but that seems excessive here...)

Suggestions appreciated.
