Look at this FAQ. if you do not need a simatic Net Device like OPC Server or WinAC RTX then you can use a Chapter without COCO: https://support.industry.siemens.com/cs/ww/en/view/24109937 for example HMi Station without Component Configuration. There are all Steps described with Screenshots and so on. Bye Murof
