I have a reply back from support. The VBIOS available for the RTX 3070 should be the previous version, 1.0.0.1.   The title is incorrectly labeled as RTX 3070 when it is in fact a VBIOS update for the RTX 3060 Ti . 
I was excited about the new Resizable BAR support for the RTX 3000 cards, but when I checked the available updates. Only the 3060Ti, 3080 and 3090 have Resizable BAR support, the 3070 seems to be missing? The RTX 3060Ti update is mislabeled as RTX 3070 VBIOS update? Is Resizable BAR support for the RTX 3070 missing for a reason?
RTX 3060Ti, Nvidia Resizable BAR, file is incorrect?
