If they didn't change your VO for the LCI lights, you can just replace the stock lights and have them "Process Car" in NCS Expert. It'll return everything to their default settings based on your VO, no backups required.
If they did change your VO, they would need to change the VO back to it's original configuration, then "Process Car" in NCS Expert.
You would need to ask your coder exactly how they did your LCI retrofit.
