Make NVIDIA gpu as a default gpu

I am using **Manjaro 20** gnome. When the linux is installed in my machine. A **Nvidia** driver was installed with **mhwd**. But lspci command does not show any nvidia gpu. **command:**

lspci | grep VGA

**output:**

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)

Any other commands like,

sudo mhwd -i pci nvidia-linux

or

sudo pacman -S nvidia

results in blank screen. Also **nvidia X server** does not shows any **openGl** or **x-screen** menu. Driver manually downloaded from nvidia did not work. machine is using intel gpu.

mhwd --listinstalled
