The link on the https://www.intel.com/content/www/us/en/products/boards-kits/nuc/kits/nuc8i7hnk.html NUC8i7HNK product page under Support section "Download software and drivers" points to NUC6i7KYK drivers. As a side note it would be great if the bios update procedure would clearly indicate if an update .bio file is not for the particular model. Now it just silently fails on restart without any error messages. I think this check should be implemented when selecting the file on F7 menu.
