Hi Karunakar, According the UEFI Spec, the Ip4Config2DataTypeManualAddress, Ip4Config2DataTypeGateway and Ip4Config2DataTypeDnsServer configuration data are not allowed to set via SetData() if the policy is DHCP. So, the clear feature is only for the manual configuration. This is our design purpose and also the reason why the feature is not apply to the Ip4Config2DataTypeInterfaceInfo/Ip4Config2DataTypePolicy.
