Do you know if they sell this kit without the SSD? https://eshop.macsales.com/item/OWC/K27IM12HP1TB/You're welcome
On the MacBook Pro subforum, there's a 61 pages thread of people using the adapter along with custom drivers and hacks to get M.2 NVMe SSDs working, along with various workarounds for certain issues.
That's why I wouldn't recommend it.
