The easiest way to figure out what changes a setting like this is making on your computers is to use PacakgeMaker and have it watch for a “Snapshot Package” while you make the configuration change. Then you weed through the files that were changed while making the configuration change, and figure out what the best approach to distributing that change is.
If the change is fairly simple, and you don’t think that overwriting those files will clobber anything else, then you can use the product of the “Snapshot Package” in InstaDMG.
I honestly have never done this particular setting, so I can’t say how it will work out, but this would be the approach.
