I have had debian on my work laptops (3 of them, they where current gen when bought) for 10 years, the only issue I ever had with drivers was a printer driver and the supplier had a .deb on their website.
Not everybody needs specific software and drivers, most people use the integrated microphone and camera of their laptop in their calls and that is about all that matters. Debian is pretty good at supporting the integrated stuff.
Of course some OEMs work better than others, butthe widely available brands, which also correlate with the most users are usually well supported.
The drivers are part of the kernel in linux, that is why you won’t find them, in most cases your kernel either supports the device or not.
Never had such an issue, especially on asus, and I did have a couple asus laptops to maintain
