How can I disable the Nvidia GPU on non-DE CLI Debian laptop and keep the intel iGPU only to keep the heat down?
I'vs seen the option to disable nvidia graphics in the bios on other laptops but I don't have it on my Alienware M14xR2. I have ths newest bios installed (A14).
You can turn it off in your bios settings. Leave the intel GPU active only.

On Windows if you set the maximum power saving for the PCI express devices the GPU doesen't even show diodes informations in hardware monitoring program so it's basically turned off. If you find an option like that in Linux you're set.
You should be able to go into the Nvidia control panel and under 3D settings, select Integrated graphics for the preferred graphics processor.
Yes I know but how can I do it in a system without a desktop environment?
sudo prime-select intel
sudo prime-select nvidia
-edit, ermm i should mention this requires the nvidia binary driver + nvidia-prime installed. If for some reason prime doesn't work for you, dig up the info on coolbits and force downclock it to keep it stuck at low power 2d clocks (and ~10-15c cooler)
