@DELL-Chris M I somewhat disagree with you. But the main issue is the incorrect description on SupportSite. First driver which OP is getting doesn't have RTX 3070 in it's description .
While nVIDIA is known to release a single driver which will work with most of his graphic cards making the driver file unnecessarily large. Dell has actually posted separate drivers for RTX and GTX series
The driver OP should be getting is listed below as per your support site,
