Prevent Mac from stealing USB mount?

I have an embedded development board that presents a USB mountable filesystem when plugged in, and MacOS (Mojave v10.14) duly mounts it.

The problem is that if I ask MacOS to unmount the filesystem, it automatically re-mounts a few moments later, and thus prevents my Windows image running under VirtualBox from gaining access to the USB.

Is there an easy fix for this?

Add a USB filter for the board.
