Implement a remote render machine

Hello team, I have two PCs with rtx 2070 cards, I try to use them simultaneously, one to render and the other to work. The Remote render section says “The Render Remote option also allows you to implement a remote render farm while still preserving in-editor renders for quick previews while you adjust settings”. I feel lost, could you help me implement this configuration?
The project is cinematic quality with ray tracing in real time. And the PCs are connected by network cable
