I've used the wedge files before, unless something has changed they
just need to exist in /etc, i.e.

/etc/dhcpselect-wedge-dhcpd.sip0
will force sip0 to be a dhcp server (not a gateway)

/etc/dhcpselect-wedge-dhclient.sip0
will force sip0 to be a dhcp client (and act as a gateway)

I don't know if any of this has changed with the newer configuration
utilities (are those ready for prime time, is there a primer
somewhere?)
