You can use the Basic Z-Wave Tool driver to set the parameter, then switch the driver back. You pretty much have to, since Basic Z-Wave Tool doesn't really allow regular use of the device (only its special commands). Some drivers might overwrite something you do with the Basic Z-Wave Tool, but that's not likely unless the driver knows about a parameter and needs it set a certain way to make the device work how the driver expects. I would still avoid hitting "Configure" after you switch back, despite the regular advice--no real reason to when all should be set already if you were using this driver previously.
I will also update my custom driver with the new parameters as soon as I get a chance to test things out.
