There seem to be several individuals making the claim that you can boot linux if you disable secure boot I have heard zero people claim that linux can access the internal device.
As far as I can see all primary sources are saying the same things. Then people who don't have the hardware are misreading said reports and spreading misinformation.
I don't have the hardware either so I can give you no direct report myself. I just bothered to read what people are saying instead of skimming and guessing.
