Adapter for Fusion drive SSD? Can I use it as a flash drive?

Hi!

I’ve upgraded my 2017 Fusion Drive iMac with 2 SSDs - one connected to SATA and one to the PCI port via an adapter.

Now I have to spare drives. The HDD is easy to use in any PC, but what about the SSD (the one paired for the Fusion Drive)? Is there an adapter to anything common, that can make the SSD usable as a flash drive?

Thank you!
