Hi Micheal, Thanks for the feedback! After some digging, it looks like kea set some specific apparmor restrictions that limit what changes can be made to the configuration, and that's what's blocking me... on this one anyway.

Clearly I'm missing something in the > systemd service config... any help here is appreciated. If memory serves me right, Kea runs under its own user (_kea ?) and it may not have access to that directory. See with systemctl edit --full kea-dhcp4-server what it uses for defaults. Your current service file is an adjustment against that. ... Granted, I have only passing experience with Kea so far.
