Changing system default graphics card

I'm currently using Ubuntu 22.04 in my notebook Lenovo Gaming 15AH05, with no extra monitors. Recently I installed the Nvidia drivers and when I run the command 'nvidia-smi' this is the output:

I also created a pretty default xorg.conf file using the command 'nvidia-xconfig' creating this result:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 525.85.05

Section "ServerLayout"
    Identifier     "Layout0"

EndSection

    Option         "ZAxisMapping" "4 5"

    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

And this is the result of the command 'lspci | grep VGA':

01:00.0 VGA compatible controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] (rev a1)
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c6)

Now, when I access Settings > Details > Graphics it says: 'NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] / RENOIR (renoir, LLVM 15.0.6, DRM 3.47, 5.19.0-35-generic)'

So I can tell it's being recognized, but when I access a videogame (Factorio in this case) and modify the sprite graphic quality to 'High' it says 'We've detected that your graphics card only has 512mb of memory...' (Even when I try to run it with Right click > Run with dedicated graphics card)

So I'm wondering if there's a way to properly set the xorg.conf file to make my dedicated graphics card the system's default graphics card, or perhaps a better approach to this situation that would serve as a better fix.
