Not easily. The Bluetooth is in a sense a USB device that is captured by OSX at system boot, from the bluetooth kernel extensions and daemons. The instructions to disable them vary from OSX version to OSX version. I have not made a "collection" of the various services that have to be disabled, per OSX version, and neither is a FAQ out there, AFAIK. So your best bet at the moment is to search with your favorite engine for "bluetooth max osx site:forums.virtualbox.org". If I get something more, I'll let you know...
