Annotate image without any specific lines

We have completed the annotations, but we don’t need any specific lines. Can we exclude any portion during the annotation process?

Example:
The switch plug is unnecessary in the kitchen image and should be removed. When annotating, it appears as though the line is present.

You can use the preprocessing “modify classes” to generate version without a class.
