Networkcard not recognized (Intel NUC8i5)

Hello,
I have a Univention Server running on a normal PC but wanted to switch to an Intel NUC for the benefit of lower power consumption. My Problem is that the network adapter is not recognized during the first setup. It should be an I219V from Intel and the drivers should be included in the installation image.
After it would not work I installed XCP-ng server on the NUC and it worked perfectly, Windows also recognizes the adapter.
So is there a way that I can fix this? I tried to install the Intel drivers for Linux (https://downloadcenter.intel.com/de/download/26012/Intel-Netzwerk-Gigabit-Basistreiber-f-r-FreeBSD-?product=82186) during setup when the system asked for drivers but it won’t work either… Does someone know how to do this properly?
Thanks for any help
Malte
