A basic DHCP setup will not do to be secure against spoofing.

DHCP security related options like i.e. IEEE 802.1X / RADIUS are required
to be secure against such attacks.

And this requests to have IEEE 802.1X in the switch and a RADIUS server
up and running. This is more complicated that a simple DHCP setup.

BTW: static addresses are not secure against spoofing either ;-)
