Well-known dhclient utility allows you to add arbitrary set of DHCP options
sent to the server and not to assign obtained lease to an interface if you don't want it.
Make sure you read dhclient.conf(5), dhcp-options(5) and dhclient-script(8) manual pages
bundled with dhclient package. The dhclient-script(8) page documents dhclient-enter-hooks script
you may create and use to override default contents of shell functions like add_new_address()
that do real job adding IP to the interface.
