No, you have to check PI spec volume 5 section 7.3.1. 

EFI_DISK_INFO_PROTOCOL is defined in PI spec. it's available and is useful for 
BDS/upper app to show up disk info, such as the disk model string.

Apparently this protocol is defined in EFI 1.0 and thus not supported in 
standard EDK II. I think you should use another newer protocol that got 
replaced by it -- don't know which, though.
