How to disable Nvidia graphic card?

My laptop is Dell Inspiron 5501, with two graphics cards:

  • GPU: Intel Iris Plus Graphics G1
  • GPU: NVIDIA GeForce MX330

OS: Manjaro Ornara 21 KDE. My BIOS version is 1.4.3. I have no idea why Nvidia is working even if I coding. I found that its temperature is 45*C. I’ve try to find something in BIOS, but this new version is so confusing. Can you help me to disable Nvidia and make Intel as primary?

You could use optimus-manager to switch between Intel, Nvidia or Hybrid mode. Be aware that for your nvidia card to be fully disabled in Intel mode, you will have to follow the guide to power management..

I did this on my MSI laptop and managed to halve my power consumption and considerably reduce the heat.

Thanks, i will try
