If you go to the LCM coding menu in PA Soft, you'll see these check boxes for hot and cold check. Just uncheck whatever you don't want scanned at startup (cold check) and intermittently while driving (hot check). Those are what give you the flicker.
This isn't my image, but it shows the hot/cold check options as they're preselected from the factory. I only disabled it for the front turn signals and left the BC message box checked, assuming that's your error message when it detects bulb out.
