There are no drivers required to support your processor in this configuration. The only drivers related to the processor are for the embedded Intel HD Graphics/Intel HD Audio solution -- but, in your case, this embedded solution is disabled because you have the NVIDIA card installed, so the Intel drivers are not necessary (and, as you have seen, will not install because this solution is disabled).
All that said, there are drivers necessary for the Intel H270 chipset as well as other Intel/non-Intel components on this motherboard. You should be downloading and installing *all* of the driver packages for your O/S version that Gigabyte is making available for this motherboard on their web site.
Hope this helps,
