Hi All,
Please try with the EnableBrightnessControl =1 as kernel parameter or add it in xorg.conf file.
You can add it in device section as shown below -

Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    BoardName "NVIDIA RTX A3000 Laptop GPU"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

After change in the xorg, please uninstall / install the driver.
