I just got one of these Lexar F35 drives. It was about 30 bucks. It might do what you need. Some things: 

- It does require Windows to set up, unless someone smarter than me can make it work in Wine. The app seems simple.
- Fingerprint programming is easy and fast.
- Users get assigned roles as admin or "other users." Admin can add and remove users. All get access to secured partition.
- The app lets you choose the size of the secured partition. I got a 64GB drive and it will partition all of it secure if you want.
- It unlocks the secure partition on Windows and Linux.
- I could NOT get it to unlock secured on Android phone (Pixel 8). Tried external powered hub, also. 
- I abused it a little by yanking it during write, startup, etc. and it didn't lose anything.

If you want me to try anything else, let me know.
