What I am really trying to do is have a comparison with the system on and off to see just how much of an impact it has on ride quality

No it cannot.
I was skeptical of MR before I drove one. So I did an immediate comparison between the current truck I owned at the time, and the 2017 I eventually bought. Drove them 5 mins apart, same roads. Details - both trucks are/were stock ride height, stock suspension, no modifications at all:
Truck I owned before trading:
2014 Sierra Denali 6.2 A6 Crewcab 4x4 - 20" Factory Wheels
Truck I test drove and bought:
2017 Sierra Denali 6.2 A8 Crewcab 4x4 - 22" Factory Wheels
NOTE: Just the 22" wheels put the 2017 at a ride quality disadvantage before my comparison even began.
My wife was with me, and we both noticed a much better ride. We purposely drove both trucks on rougher streets to get a feel for how the suspension absorbed potholes, cracks, heaves, etc.
The MR does not take away the movement associated with running over a bump/crack. The suspension still communicates road imperfections. What it does well - is reduce the harshness of how the bumps and road imperfections hit the truck. It's a bit hard to describe unless you drive one truck with and one without. That is the best way to experience it.
Fast forward 3 years to today. My work provides a 2019 Silverado 5.3 A8 Crewcab 4x4 LT - 18" wheels (decent options, but no leather - heated seats, heated wheel, NAV, etc). I drive it daily to work and only drive my Denali occasionally - mostly when I need to the box for room to put stuff. That said, every time I drive my Denali, I immediately notice how much smoother it is than my work truck - it's night and day better. Again, this is with a significant sidewall disadvantage as the work truck has much smaller wheels.
If you daily drive a Denali - you will lose the sensation of the smooth ride after some time. It won't be until you ride in another truck without MR that you will realize how much better the MR in the Denali really is. I truly don't get the owners who delete their MR system because the shocks cost more. First, they should, they are an active damping shock. Second, why not buy an SLT or other truck if you don't want the Denali options anyway?
