The two have absolutely nothing to do with each other.

You have identified the problem yourself:

From what I can tell, the DHCP update script is running successfully and
then the client is attempting to update its own DNS immediately
afterwards.

If you are using DHCP to update the dns records, you also need to stop
your clients from trying to update their own records, something the
wiki page warns about, but not obvious enough. I will fix this.
