=> I can see at least two easy ways: use a firewall (the flag is at a fixed offset so trivial to find) or write a hook for Kea (install it at the pkt4_receive callout point and return DROP when the query4->getFlags() has FLAG_BROADCAST_MASK set). As the broadcast flag has a function in the protocol perhaps it is possible to tweak the configuration so they failed to be served (e.g. responses do not reach them) but a direct way is more reliable.
