I installed SteamOs on ROG Zephyrus G14 GA401QM_GA401QM I have a dedicated GPU and an iGPU I only see steamOS reading the iGPU. Any idea how I can get my NVIDIA gpu to work? I went into a game and it doesn’t seem to use my dedicated gpu I also don’t see it in hardware information

Steps for reproducing this issue:

1.download steam os and format computer to run steam os
2. Check hardware info to see if it reports dedicated gpu.
3. Run a game and see it using the integrated GPU

Research direction

Start by reproducing the report on the ASUS ROG Zephyrus G14 using the listed SteamOS version: check Hardware Information, then run a game and observe which GPU it uses. Done means SteamOS reports the NVIDIA 3060 and a game can use the dedicated GPU; the issue does not identify files, tests, or an entry point.
