Suppress PnP driver Installation Pop-up

I am using DPInst.exe that comes with the windows DDK to silently install an unsigned driver for a PnP device. I would like to know if there is a way to suppress the driver installation window that pops up when you plug in a PnP device. Another possible solution would be to kill the installation app from mine, but I don't know how to detect and kill it from another process.

Thanks,

After a researching it some more, there doesn't appear to be a way to stop the automatic installation wizard. I can detect that it is running and then I need to stop my installer and then have a co-installer that is tied to the finish page of the default installer via the driver that is being installed. Once the finish button in the installation wizard is clicked, my co-installer will be invoked and I can either accept the drivers that were just installed or reinstall the specific drivers that my installer would have originally installed.

Below is more information on it that is probably a lot clear than what I just typed.
