Per PI 1.2 errata B spec, for SetMemoryAttributes() service of CPU Architecture Protocol, EFI_INVALID_PARAMETER should be returned for cases:
If Attributes specifies a combination of memory attributes that cannot be set together, then EFI_INVALID_PARAMETER is returned. For example, if both EFI_MEMORY_UC and EFI_MEMORY_WT are set.
