This has nothing to do with PLP. If the drive reports PLP then Flush is allowed to be a no-op because all acknowledged writes are durable by design - the OS need only wait for the data write and FS metadata writes to complete without needing to issue a special IO command. This is covered in 5.24.1.4 in the NVMe spec 2.0b
