Answer
Under the DHCP tab of the client, you can edit or add an additional custom option.
Option 42 - NTP
Note that this field just requires the IP address. In this case 10.1.0.1 is represented in hex 0a010001
Option 50 - Request a Specific IP Address
Option 61 - Client Unique Identifier
Option 119 - Domain Search
Note that this field needs additional values that represent the length of each string and a termination of 00.
You may want to check the specs or other sources
Below is an example for domain spirent.com.
option 119 should be set to hex and use 0773706972656e7403636f6d00
The break down of 0773706972656e7403636f6d00 is:
07 (7characters, spirent)
hex conversion of spirent = 73706972656e74
03 (3 characters, com)

00 (represents the end)
