Hi, just wondering if anyone can assist with an explanation or sources of M.2 SATA/NVMe commands and their differences and how they effect the measurement of uncertainty in respects to imaging for ISO17025.

That sounds like the kind of rubbish you get from a UKAS assessment. Measurement of uncertainty is not really a thing with imaging a hard drive, despite what UKAS tries to fit in. They actually struggle to define what the measurement is.

You get x number of sectors not x +-10%. If you have unreadable sectors, that also certain i.e. you have 1 bad sector. As you have to put something in the uncertainty box, just use times recorded as part of the imaging process can be +- 1 minute
