is there anyway to install the driver ?


That seems to be the rtl88x2ce. That means you need this AUR package:

For that you need the kernel headers for your installed kernel first, but:

Is EOL = end of life. You should consider 5.4 as is LTS, or go with 5.8

To install the headers once you made sure you updated the system and rebooted:
sudo pacman-mirrors -f && sudo pacman -Syyu
Run this command

sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')

Reboot again
Then you run
pamac build rtl88x2ce-dkms


Thank you. it worked like a charm.
