How can I control Client pawn from the Server?

I’ve been trying to make a presentation in UE4 and I can’t figure out how to control a pawn on my presentation screen from a Windows 10 tablet.
The setup I was thinking is based on two Windows 10 systems, one is a pretty powerful one running my 4K presentation screen in First Person Perspective and the secondary one would be a Microsoft Surface tablet with a top-down view for navigation. Everything will be connected to a private network made just for the these two systems.
Can anyone provide me some input on this?

Use UDP Sockets, so you send info from tablet to 4k presentation, with input commandS>?

Can you, please expand your answer? I am somewhat of a noob on the networking front. Could you recommend a tutorial or a guide on doing this? Or any kind of documentation?
