How to set up system wide variable on log in to fix slow launch of chromium based apps on non-nvidia devices

Finally solved it by myself:

STEP1:

Create ~/.xinitrc and ~/.xprofile files as described here:
https://wiki.archlinux.org/title/Xprofile
and paste this code inside the ~/.xinitrc :

#!/bin/sh

# Make sure this is before the 'exec' command or it won't be sourced.
[ -f /etc/xprofile ] && . /etc/xprofile
[ -f ~/.xprofile ] && . ~/.xprofile

STEP2:

Paste this code inside the /.xprofile :

string=$(inxi -G | grep 'NVIDIA')

if [[ "$string" =~ .+NVIDIA.+ ]]; then
    echo "True"
else
    echo "False"
    export VK_DRIVER_FILES= 
fi

It checks if a Nvidia GPU is present in your device and sets the VK_DRIVER_FILES= environment variable accordingly.

This solves the issue with slow launch of chromium based apps, when running Endeavour OS on a device without Nvidia GPU.
