iPXE will normally send the system UUID as part of option 97 in all DHCP requests. If you need to prevent this, you can override the system UUID with an invalid value. For example:

  iPXE> set uuid:string INVALID
  iPXE> dhcp                      # Option 97 will not be present in the DHCP request
1) DHCP option 97 contains a single zero byte followed by the 16-byte system UUID
