PSPP is PCIe Speed Power Policy and has nothing to do with PSP.
PSP can’t be disabled, as it performs critical platform initialization tasks like memory training and S3 resume. Sometimes there’s an option to disable it’s MMIO device so it gets inaccessible for the OS and main CPU, but PSPP is certainly not that option.
