Hi, I also have the same problem. I can't use the Elan 1200 touchpad of my Asus X441U laptop in graphical install mode for the stretch and 20200808 netinst images. I haven't tested on the buster and bullseye alpha 2 images, but considering that my touchpad doesn't work on the latest daily snapshot of netinst, I assume it won't work with the buster and bullseye images either. Here are some logs from my installed system showing the touchpad I have:

But others who are installing Debian on their laptops might find it annoying. I suggest adding this bug to the buster and bullseye erratum, like "Touchpad not working in graphical install".
