There are one or two places that can swap the units but it's big money. It can be done but it's going to cost you a lot of cash.
Unfortunately all those cheap RNS 510's flooding the market on eBay for previous generation Golfs were from illicit sources and a huge corporation like VW weren't going to let that go on forever, so they put component protection on new cars which means that even dealers (who are basically just franchises all over the world - meaning not all will be too fussy about what work they undertake) aren't able to bypass the coding. It's a factory only job.
Similarly warranty claims from owners with third party ECU software through dealers that openly marketed third party software means any warranty diagnostics now get sent direct to Wolfsburg and hence we have the TD1 paranoia.
