Only Intel graphics on hybrid Nvidia laptop

Dear Archers,

I have a Lenovo X1 Extreme 2nd Gen with  Intel i7-9750H
The system is KDE and X11.
This is the current graphic configuration.

❯ inxi -Gxxx
Graphics:
  Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] vendor: Lenovo
    driver: i915 v: kernel ports: active: eDP-1 empty: none bus-ID: 00:02.0
    chip-ID: 8086:3e9b class-ID: 0300
  Device-2: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] vendor: Lenovo
    driver: nvidia v: 510.60.02 pcie: speed: 2.5 GT/s lanes: 16 bus-ID: 01:00.0
    chip-ID: 10de:1f91 class-ID: 0300
  Device-3: Chicony Integrated Camera type: USB driver: uvcvideo
    bus-ID: 1-8:2 chip-ID: 04f2:b67c class-ID: 0e02 serial: 6726
  Display: x11 server: X.Org v: 1.21.1.3 compositor: kwin_x11 driver: X:
    loaded: modesetting,nvidia alternate: fbdev,intel,nouveau,nv,vesa gpu: i915
    display-ID: :0 screens: 1
  Screen-1: 0 s-res: 3840x2160 s-dpi: 96 s-size: 1015x571mm (39.96x22.48")
    s-diag: 1165mm (45.85")
  Monitor-1: eDP-1 model: AU Optronics 0x42eb res: 3840x2160 hz: 60
    dpi: 284 size: 344x193mm (13.54x7.6") diag: 394mm (15.5") modes: 3840x2160
  OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2)
    v: 4.6 Mesa 22.0.0 direct render: Yes

The Bios permits only two choices: Hybrid Graphics or Dedicated Graphics, not Integrated only.
So it seems that I cannot disable the Nvidia graphic card.

For my needs, the Intel integrated graphic is enough.
For heating and power management, I would prefer to use only the Intel chipset.
Is there any software way to achieve this goal?


I love archlinux: the last STABLE kernel release + the last STABLE DE release + the last STABLE apps releases. The upstream developers decide what is STABLE.
