Dell Touchpad 5420 Can't install

Same issue as another user here but there was no posted fix. The Touchpad Works!!  There is no settings to open anywhere to enable 2 finger touchpad scrolling.  No Touchpad Driver showing on Dell Drivers for 5420.  I updated the Chipset and rebooted as the Dell Chat recommended. I found the Alps Dell Touchpad driver online in a search, but of course that didn't work as it was probably for another laptop. No touchpad icon is showing in the taskbar. This is a re-imaged laptop with 20H2 at a school with most drivers. We do not use Windows updates to update the laptop. A full image with drivers is installed, but when something is not working, we get it off Dell. There is no Driver! 

Help!!
