That's not quite correct. Fifth is an actual gear. Putting it in manual mode takes away the MDS. Hitting the Tow/haul button takes off O/D which is electronic.
This is for those that have the ability to switch to a manual shift mode. If your Ram doesn't have that option, then I do not know how to turn off the MDS.
I originally thought using the Tow/haul button did it but was corrected during the Engineer chat which I why I made the original post in this thread.
