PlatformConfigSupported: Whether the platform level configuration of persistent memory modules can be modified with the host software. One of:- 0: Changes must be made in the BIOS.
- 1: The command Create Memory Allocation Goal is supported.
Alignment: Capacity alignment requirement for all memory types as reported by the BIOS.AllowedVolatileMode: The volatile mode allowed as determined by BIOS setup.
