The tool's setup can be done in two ways: with a GUI and without a GUI. You can install the GUI. You download the base image, and during installation, it will ask you whether you want just a plain server or a server with a GUI. It will give you all the options, including whether you want a non-graphical user interface normally used in enterprise environments.
You don't need any GUI in enterprise settings because those servers are installed and managed without it. If you use the GUI, it will consume more RAM and CPU. However, if you use just the simple non-GUI version, it will use fewer resources. On the server side, people typically don't use the GUI; they only use the non-graphical user interface because it is sufficient for running the server. On the desktop or workstation end, you can have the GUI installed.
If a system is the latest one, with a high-end CPU, a good amount of RAM, and SSD drives, it should not take more than ten minutes.
