I've found 2 sites with registration information of I-PACE's:
The Netherlands; https://www.rdwdata.nl/merken/jaguar/i-pace
https://kenteken.tv/hoeveelzijnernog.php?merk=JAGUAR&merk2=&voertuigsoort=Alles&filter=I-PACE
Norway: http://www.itanywhere.no/E-reg.php?car=Jaguar%20I-pace&mnd=%25&year=2018
Please add if you have found some more!
Edit:
I've created an visual report for the registrations in the Netherlands in PowerBI with data straight from the vehicle registration (RDW):
