If Pi-hole's DHCP is disabled, you should not see any such message.
There may be other software running on your host employing dnsmasq, or at least trying to configure it.
Run from your machine hosting Pi-hole, what's the result of
sudo ss -tulpn sport = 67
Also, please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:
Thank you for your reply. Was able to correct the issue. Fortunately there was not another DHCP Server running, however, there was a misconfiguration on the box running pihole. The setting for the static IP Address was set to "inform ", instead of "static ip_address "
Made configuration change and restarted. No longer seeing the DHCP Inform Messages.
