Months? Yuck! Checked PTS for service bulletin related to just this code but don't see one. There is a SSM 51891 related to SCR for other codes though. Do you know what they have replaced so far?
Sounds like you followed the ppt rd to a t. I got burnt on that code before, on a 2021 f450 with 30k miles. in the end, what fixed it was an OEM air filter. It came back 3 times, I regen and reset specified functions, the funny thing was that the filter looked good no tears or any other abnormal characteristics. I went with the air filter because the fleet that services it uses cheap ass filters and the problem started after it was replaced. I have also seen that code come up with the wrong oil not rated for diesel.
Nice video guy
Have a 23 that’s been in the shop for months now with this code.

Yep, exactly right. Great to know about the air filter and oil. This code can be a major PITA!
