There is no converter from NVMe to SATA. Full stop.

The m.2 connector (for the SSD) has 2 possible protocols, SATA or NVMe, defined by the B or M key. Only the m.2 SATA protocol SSD can be converted to the cabled SATA interface. The m.2 NVMe protocol SSD won't be able to be plugged into the slot, as the key will be different.

You may have luck if you can find a PCIexpress interface card that fits a NVMe m.2 SSD, but it depends on your mainboard if it can boot from the PCIe card.
