It is more or less specific to different brands. But restart the computer, enter the BIOS and look for it in some menu. Or google for it, with respect to your computer model.

ex.
disable gpu in bios <your computer and model>

Hopefully there will be a setting to disable the dGPU, but not all BIOS provide it.

Is this a laptop? i.e. outputs are connected to a single video card.
If your machine has separate outputs, then make sure cables are connected to the motherboard rather than the dedicated (did you made a type? It looks like it’s Nvidia, not Intel)

Also, do you use Xorg or Wayland?

If you have Nvidia proprietary drivers (do you?) then execute nvidia-smi to show any processes running on Nvidia.

Your OP says little about the current configuration, omitting everything about software. Better info should make a useful response more likely. Complete input/output pasted here using PRE tags (</> icon above input window), from running the following in a GUI terminal, should do that:
