SE Live Silent Install

I'm currently creating a Windows install iso for my streaming PC and i'm looking to add SE Live into the custom ISO and couldn't figure out how to install it silently. I tried the /S parameter and it still requires interaction. I know I can just install it once I have the system booted, but would like to have it set up automatically during the OS installation. I'm currently waiting on my PC parts to arrive, so I'm creating the image on a VM.
