You should change the producer name with the MavicPro one (in two places). I do not remember the exact strings, but you may open binary two raw files, one from MavicPro and one from Mavic 2 Pro. Take care to not change the name length, use/keep spaces instead. Better if you find someone to write a short program for it.
I wrote a program which changes this, but I have no permission to distribute it. Maybe there is some programmers on the forum and the above hints should be enough for them.
