It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
DHCP leases are not given out on a per user account basis, only per computer. The only way I know of of not giving a computer a DHCP lease would be to give the computer a static IP address outside of the DHCP scope
IP addresses are assigned to network interfaces on computer, not to users. To answer your question as you've presented it: you can't.
If you'd like for a specific computer to not be assigned an IP address by a DHCP server, you can accomplish this a few ways. You can put the computer on a vlan/subnet that doesn't have a DHCP server on it. Don't enable DHCP Relay for that subnet and you're fine. Or, just assign a static IP address to the interface in question.
