There are few applicable protocols which are missing for selection in IHV SCT e.g. EFI_HII_CONFIG_ACCESS_PROTOCOL, EFI_FIRMWARE_MANAGEMENT_PROTOCOL when compared to generic SCT. 

These protocols can be ported to IHV SCT..

Can anybody help me to understand if there is any limitation/issues for enabling these protocols for IHV SCT? 

Thanks,

Jabir
