About 3.5 inch Touch Screen :

You need to configure the driver to use this touch screen, support Raspbian/Ubuntu/Kali-linux system.(Ubuntu just support RPI 3B/3B+, doesn't support RPI 4B )

Please use our recommended system for touch screen. If you use other systems, it may not have touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with our touch screen.

Here is the link to download the system image which already configure the driver ( at the end of link ):
