You can search "nvme enclosure" on ebay if you want to go that route.
Just get the right "M-key" / "E-key" for enclosure to match the drive.
I've done ok with fairly cheap no brand ones 10-20 USDish - maybe a year or so regular use.
For my laptop i have a slightly bulkier one that also has 2x usb-A ports so it expands connectivity too.
Don't use sd card / usb flash unless it's only option (mobile phoine / tablet).
