Hello @David van der Eng ,
Welcome to the Microsoft Q&A platform.
Unfortunately, you cannot change the region of the ADF.
Note: If you want to move your Data Factory to a different region, the best way is to create a copy in the targeted region, and delete the existing one.
For more details, refer Copy or clone a data factory in Azure Data Factory.
Hope this helps. Do let us know if you any further queries.
