How to move DB

I have home assistant os running on a raspberry pi 4.
I followed the installtion instructions and most of my devices are up and running, what I would like to do before going too far is move the database to a usb stick rather than it being on the microsd, is this possible and if so how do I do it?

Configure Recorder to use the new location.

Challenge is to identify/predict the USB stick mount point with Home Assistant OS.
