No boot config file (hw_intfc.conf)


I want to plug my lcd screen on my rock pi 4 B+.
On the wiki it says there is a config file to modify in /boot/ but that file isn’t there.

debian_version : 10.12
uname -a : Linux rockpi-4b 5.10.103+

I still tried to run the pi with the screen but nothing shows.
The xserver-xorg-video-fbdev is installed and up to date.
