[470.63.01] xorg.conf issue on Kali with multiple monitors and laptop display

I have the following setup:

Kali: 2021.2
Nvidia driver: x86_64-470.63.01
GPU: GeForce RTX 2060 Mobile (rev a1)
Laptop: Legion 7 15IMH05

The issue is that I’m using a 4-monitor configuration (3 external monitors and the laptop’s display), but only the external ones are displaying anything, while the laptop display is black.

From what I’ve read it seems that using both laptop and external displays is something considered Optimus system and I should configure something called PRIME.

I tried replacing my xorg.conf with this one Official driver 384.59 with GeForce 1050m doesn't work on openSUSE Tumbleweed KDE - #2 by generix but X just crashes

The only thing that did something was removing xorg.conf at all and create a file called `/etc/X11/xorg.conf.d/20-nvidia-myoptions.conf, containing

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia"
    Driver "nvidia"

as explained here PRIME display is not detected after generating xorg.conf file .
This did activate my laptop display, but however it disabled all of the 3 external monitors turning them black.

The following commands outputs as follows:
