Welcome to the Community,
if the integrated network adapter isn't supported (seeVMware Compatibility Guide: I/O Device Search), your options are either to get a supported network adapter or - since you mentioned learning purposes - to consider installing a virtual environment based on VMware Workstation, which even allows you to setup multiple virtual ESXi hosts, vCenter Server, ... Take a look at e.g. Building the Ultimate vSphere Lab for a sample setup.
