How to back GUI mode from CLI

I want to build a TV server on my raspberry pi but I still need config something on GUI mode. However, I have no idea which command can take me back and I don’t want config again in raspi-config

I’m not sure I understand - can you expand on from where to where you want to go, and after doing what?

Sorry I haven’t enough time to check the forum
