Swapping Gen-4 ECUs 1537264-00-B with 20-B to get V3 CCS2 Superchargers to work.

Hi,

I own a Model 3 2022 with NACS port, comes equipped with a Gen-4 1537264-00-B.
In my region, Tesla's V3 Superchargers are CCS2 configured, and my CCS2 to NACS adaptor doesn't work on V3s, though it operates smoothly with public CCS2 non-Tesla chargers.
1. Considering my ECU is a NA/US version, I'm curious if a 20-B swap would be a viable solution? (One of my friends tried doing a software update after the swap, but the software update failed to complete)
2. Any experiences or insights from others, particularly those who have successfully used a Gen-4 to Gen-3 ECU swap to have CCS2 enabled?

Anyone with similar experience?
