Windows Mobile...enable/disable barcode symbologies with a REG file

A quick question from one of our Partners:

For the MC3190 (or any Windows Mobile Device), is there a way to enable or disable barcode symbologies in the Registry by using a REG file?  There are several 'ReaderParams' settings throughout the Registry with a long list of 00 HEX values.  Seems like these could be barcode type flags?
