When you use LAN automation to bring up the fabric underlay, all switches should be treated the same way. Only once the fabric underlay is up and all devices are added to DNAC, you then start provisioning fabric overlay and assign device role. The DHCP server device uses for initial communication is configured on the seed switch by DNAC so there is no need for external DHCP server. This is demonstrated in RS0118 video.

Thanks for posting this on my behalf.

Is there a place for initial lab configurations?

Because if I understand you correctly, since all that was initially configured on BC2 was default routing, SNMP and local username/password we need to configure the same (all three) on other fabric members to be discovered and provisioned? And that includes pair border and edge switches.
