Can I service my new car at an independent garage without voiding the warranty?

Is it true that to ensure the validity of a vehicle's three-year warranty, you have to have it serviced by the supplying main dealer? I've just bought a 12 month old Jaguar F-Pace with two years warranty left. I'm told that there has been a case which has ruled in favour of using private garages for servicing as long as the vehicle's genuine parts are used.
The EU ruled that manufacturer's warranties had to apply whoever serviced the car, but, of course, it has to be serviced precisely to the requirements of the manufacturer and that has to be fully documented and invoiced. If it isn't, the manufacturer can void the warranty. Also, of course, getting it serviced independently means you miss any technical service updates that only dealers can do.
