Yes, the CVN is computed in the firmware based upon the configuration of the entire ROM (usually 1-2MB of data). So even a single bit change in the ROM after tuning should create a CVN change.
You can go into the ECU itself, but most of them are environmentally sealed and opening is, at best, semi-destructive. Doesn't mean the smog-nazis would be able to tell without looking close, but it isn't a good option.
