Upgrading NAC Wave 2 to Wave 4 - Telecoding/VIN advice needed

[Loumi01]

​Hi everyone,
​I am planning to upgrade the infotainment system in my Peugeot 308 (2019, T9) from the original NAC Wave 2 unit to a Continental NAC Wave 4 unit (part number 9843006480).
​I have already acquired a full-chip Lexia interface and have DiagBox installed. I understand the basics of the installation, but I am looking for some advice regarding the "pairing" process once the new unit is installed.
​I am concerned about the potential requirement for an online PSA token to perform the VIN coding/telecoding on the Wave 4 unit. Does anyone here have experience with performing this upgrade offline? Specifically, I would appreciate any tips or best practices on how to successfully handle the VIN pairing and configuration (to ensure the reversing camera and other vehicle features work correctly) without needing a professional online connection.
​Any advice or guidance on this would be greatly appreciated. Thanks in advance for your help!
