Can I reverse the emissions fix by disconnecting the battery?

My SEAT had the "fix", which has ruined the performance and fuel consumption and will likely lead to EGR failure in the future. Can I reset it by disconnecting the battery? Slim hope, I know.

No. I checked with Superchips. Too much is altered, including some codings known only to VAG.
