I'm completely uneducated on the N55 but my understanding is that it was developed by Bosch and not Continental like the MSD8x. So variable naming standards will vary hugely. I do have some random A2L files for various different N55 offerings but without knowing the naming it's hard to know what parameters do.
I have looked at the S55 FR and it does appear very similar to the layout for the N55. There is a parameter called "CDMD" with the description "Switch off code word DMD (EURO coding), CD..=0 -> no diagnosis". In the N55 ROM "7982780B" that parameter is at address 0x801B59BB, but as usual with leaked A2L files, there isn't one for your 98G0B.
That looks as close as any other parameter to being a straight up disable. There certainly very little in common between the N54 and N55 code. The S55 would be your closest relative for R&D.
Maybe contact Jake on here about it. He will undoubtedly have much more N55 info.
