Configure gamestream service without GeForce Experience

Hey guys… Has anyone managed to set up nvidia game streaming service without using/installing/signing-in to GeForce Experience? I’ve been quite satisfied not signing Nvidia’s EULA for years while using Chocolatey to get my driver updates (cinst -y geforce-game-ready-driver), but I’m trying to get a platform-agnostic streaming service up and running. Steam link has been pretty good but I’m looking at the better app support on Moonlight and wanting to try that out. The “Host” (server) configuration steps mention to enable the “setting” (service) in GFE, but I can’t help but wonder if there’s not something open source that can support this, or at least a way to circumvent it?
