The issue is not "cracking" the ECU - it looks like Edge/ Holley will let you swap your PCM when you buy their $500 tuner

HP Tuners appears to support MDS disable as well - but you need to buy a dongle ($300), credits ($100), and ship your ECU in for modification ($250)
The issue appears to be that FCA removed the ISO command to command MDS, so you can't make a cheap dongle that sends a command and does what you want - you have to ship the ECU in and tune it. *Then* you have to ask whether you want to disable MDS bad enough to pay $500-$650
