NRF52480 DK external Supply

When I just plug the USB cable on the board I get a GPIO high voltage of 3V. But when I also put +5V on the external supply pins, the GPIO high voltages are 4.5 V. Is this normal?

And if so, how can I change it to 3V?

I couldn't find something on this topic.

Best Regards
