If you seriously think that the various cameras don't have NR corrections baked in, that is pretty doubtful, at best. Didn't see any asterix on Bill Claff for the R5, maybe I missed it. Did see the 6D ML, presumably Magic Lantern, having really high DR, I have doubts a lot of this is due to hardware
Look again - Bill Claff's data shows that the R6II, R5 and R3 are all cooking their RAWs starting right at base ISO (the downward facing triangle indicates baked in NR). This wouldn't be an issue really if the option was given to the user to disable this in-camera, but unfortunately you have no choice.
Sony and Nikon are not baking NR into their RAW files. The only real exception being that Sony does bake some in on some of their bodies beyond ISO 51,200, but not before.
How could you know no NR is applied? I don't believe that, older bodies have more noise, if you go back far enough, but it may just largely be they put NR in camera as opposed to any better hardware. Banding isn't as common vs the 5D and rebel xt, for instance, but did they actually improve the sensor and other components, or just put anti banding software in the camera, probably easy to do
The nice thing about facts is that whether or not you believe them, they're still true 
Bill has lots of in-depth articles on his website if you care to read them, and he also makes his email available if you have your own objective data that you would like to share, or if you have questions about his processes.
Some cameras bake NR into their RAW files, others do not. Some are worse offenders than others. All of Canon's current full-frame RF bodies (R5, R6II, R8 and R3) are cooking their RAWs to a degree that is obvious when examining the data. Whether or not you care is entirely up to you.
Older bodies have more noise for lots of reasons, most of them hardware - if you want an example, have a look at how much better Canon's sensors got once they finally moved the ADC on-chip around ~2015.
Glad you know it all, if you could point me to the Bill Claff article that states these non Canon cameras don't have any Noise Reduction. Not that he's 100%.
Your interpretation of a graph, does not a fact make
Canon had low noise on aps by the 2010 60D, if not the 7D. FF certainly by 2012 5D3/1Dx/6D
I have travel magazine covers and full stories (Conde Nast Traveler, T&L etc etc) photographed with medium format, full frame mirrorless, iPhones…They are indistinguishable when shot well and printed in a glossy magazine or ad campaign.
If I were able to, I would attach some images here for reference…
(Thus IMHO going berserk about minute noise differences only viewable at 400%…🙃
