Bought 5.7 hemi/nag1 out of a cop car. Some questions.

First off Happy fourth of July everyone!
So long story short I sold my 360 and 727 and bought a 5.7 hemi/nag 1 setup out of a cop car that had 74,000 miles on it. Got a great deal for it that I couldn't pass up. I've already bought most of the swap parts for my 74 duster for it. My question is instead of having to spend 1500 dollars for a new cam for it to get rid of the MDS, can I just buy a tuner like a Diablo and just turn off the MDS? Or is that not possible. I know sublime technologies sells the wiring harness that comes with a ob2 port. So I'm just trying to figure out if that can work. Here is a picture of my car and the hemi.

What year engine? Keep in mind the pre/post 2009 is year break for vvt or non. I know I have a takeout hellcat cam, and 6.4 valve springs on the shelf. PM me if interested. Literally brand new takeoff parts.
