The most efficient way to handle this is using Intel Integrator Toolkit (ITK), which was designed to support exactly this scenario. This tool allows you to create a BIOS update file that (also) includes the customizations that you created. You run the tool, input a BIOS update (.BIO) file (usually the latest BIOS available), make changes to the BIOS parameters (and also customize SMBIOS strings, add a custom splash screen, etc.), generate the customized BIOS update file and then install this BIOS update file onto each of the NUCs. At the same time that this particular BIOS update is being installed (or overinstalled), the other customizations that you made will also be installed.
Hope this helps,

Please bear in mind that we are updating all of our product’s BIOSes as quickly as we can, and we do no know exactly when the process will be completed.
