I don't have any experience with this SSD. But nvme(4) will automatically attach to any NVMe SSD that presents the the correct PCI class/subclass/PI - it doesn't need an explicit device/vendor ID in the pci_ids table. The pci_ids table is for SSDs that require quirks or to show a model-specific name. It looks like the PM1725a is actually in the pci_ids list so it should be covered either way.
