Dynamic PCDs (or more generally, DXE protocols) can be used in the entry point functions of DXE_SMM_DRIVER modules, to my understanding. Dynamic PCDs can't be used in any SMM services (callbacks, protocol member functions, SMI handlers, etc) that those modules provide (i.e., dynamic PCDs can't be used after the entry point function has returned). I'm not sure about MM_STANDALONE modules. The PI spec probably explains the environment in which the entry points of those modules are invoked.
