转到设置"->版本控制"，然后删除要从中删除版本控制跟踪的文件夹(着色选项卡等).它自然会不从项目中删除版本控制(例如删除.git/文件夹).

Go to Settings -> Version Control and remove the folder from which you would like to remove version control tracking (coloring tabs etc.) It will naturally not remove version control from your project (as in deleting the .git/ folder for instance).
