According to dhclient(8), OMAPI is used for this sort of functionality, and omshell(1) should be able to do this kind of manipulation (including "suspending" the agent instead of stopping it). You do need to set up authentication first, even for local use. Otherwise, you can always just kill and restart the dhclient.
