The panel PC utilizes a udiskie user service to automount USB drives when they are plugged into the panel PC. Each recognized partition will be mounted at /media/{user}/{partition_label}.

To disable this service, run systemctl –user disable automount. After rebooting, it will not longer start and USB removable drives will no longer be automounted. To stop the service immediately, without rebooting, run systemctl –user stop automount.
