freestyle that is not marked and is showing can be setting to invisible

I'm webtoon creator beginner. I make building in blender. but blender is not comfortable than the Sketchup. blender can't delete the freestyle line that I want . If you set the freestyle, you can see line. When you create an object, you see lines that you don't need. I can erase the mark freestyle line, but otherwise I can't make the not marked freestyle line invisible in the rendering. I would like to add a menu that doesn't show the selected line in freestyle.
