Disable DRL 2010 Mustang v6 convertible
 

I have a '10 Mustang v6 convertible. I am aware that the car I have was once a US car ... it has a MPH speedo. When I start my car the low beams come on (I am aware that in some cars, shifting the car out of neutral does that same thing). Since it is a US car, the DLR must have been enabled when it came across the border. I want to swap out the stock headlights to a unit that has separate DLR lighting (like 2018 with 'gills'). With the way the DLR works on my car, if I swap the units, the low beam will always be on with the DLR. I want to disable the existing DLR (low beams on) so I can switch on the low beams myself. I'm aware this may be possible using ForScan software, but I can't find or figure out how to do it ... ANY HELP ????
