We're happy to hear that you are interested in our product and 5G technology!
As far as we understand 5G is a hardware backed feature, meaning that devices have to have a certain component to connect to these high speed networks.
Regarding the P20 Pro it is unfortunately not possible to ring 5G in an update.
We hope this is not a huge disappointment. If you're interested in this feature, please check out our upcoming devices!
