Does the adapter require additional drivers or software?

Does not require additional drivers or software because it is a passive adapter. It simply reroutes the electrical connections from the M.2 NVMe SSD to the M.2 A-Key slot. Your M.2 A-Key slot must support PCIe lanes for an NVMe SSD to work. Many A-Key slots only support USB or WiFi modules, so the SSD might not be recognized.Modern operating systems like Windows 10/11, macOS, and Linux come with built-in NVMe drivers. Even if the SSD is detected, the BIOS may not allow booting from an NVMe drive in an A-Key slot. Check your motherboard’s boot options.
