Ok so I finally joined the TurboDuck Discord to get more info and it seems that it is not possible to decrypt the CarVSTConfig.xmb file.
That said, I'm getting some decent results even without accessing it, most likely I'll be releasing a sound pack mod in the near future.
I have quite a list of cars in mind to dedicate a sound mod to, and I've already started and completed almost 4 sounds!
Ferrari 458 Italy
Ferrari 430 Scuderia
Nissan GTR
Lancia Delta Integrale Evo 2
I won't deny that I'm doing it objectively for me more than anything else, as I hate the synthetic and soulless car sounds of the old racing games.
Which then, for heaven's sake, maybe at the time they could have been there, and also considering the large fleet of TDU2 cars, the devs certainly couldn't work miracles, indeed they even did it on some cars, objectively speaking.
In conclusion, I don't know if people are really interested in this aspect etc, but basically once I've made them for myself I'll be happy to share them, hoping someone appreciates them!
Ok stay tuned!
