This is from th edhcpd man page:

     The names of the network interfaces on  which  dhcpd  should
     listen  for broadcasts may be specified on the command line.

How you enable this is very platform specific, but essentially you want
the process to start with a prameter like this:

  dhcpd eth1

will only listen on eth1. Also see the manual page for dhcpd.conf and
search for 'local-address'.

As an alternative you can use an empty subnet definition for the
network you want to ignore, eg:

  subnet netmask { }
