You need to install the Chipset Device Software package (a.k.a. the INF Update package).
Search on downloadcenter.intel.com for the page for your NUC model. There should be at least one version of the above package referenced and downloadable from that page.
P.S. You likely want to download the whole set of driver packages. There is a ZIP file download near the top of the page that provides all of the latest driver packages.
