How to avoid dhclient default gateway on an interface

Here is an issue I have stumbled uppon a couple of times and for which I still have no solution. I have a NetworkManager managed box with two interfaces. Let's call them *eth0* and *eth1*. Both NEED to get ip over dhcp, and they both add their default gateway. What I would like is to have one of them not applying the default gw. In the last iteration of this situation I learned that NetworkManager creates a */var/lib/NetworkManager/dhclient-eth0.conf* from */etc/dhcp/dhclient.conf*. Is this a missing feature of NetworkManager or I should try to create a new *dhclient.conf* that contains dhcp request information for each iface with different request sections?
