It is not necessary to use native DHCP feature of OVN. You can always
disable it. Infact it is disabled, unless dhcp options are added to each
logical port. So it's fine to use your own DHCP server.
But note that in order for that to happen, you need your DHCP server
to listen on all OVN overlays. You could do it by running it in an
oVirt VM that is attached to all these overlays, or by adding
per-overlay VM serving as a relay. Both idea seem cumbersome in
opinion.
