I have tried various approaches including xbacklight(and other guides online to change it) but nothing worked.
xrandr command gives me Failed to get size of gamma for output default

I have intel iris xe graphics.
I had initially tried installing elementary os Hera. I wasn't able to make brightness control work and then I decided to try ubuntu 20.04. In elementary sys/class/backlight had a folder called asus-nb-wmi. In ubuntu its completely empty. Is this because there are no drivers available for my laptop graphics/video?
Output for
bash sudo find /sys/ -type f -iname '*brightness*'
