"this" seems to refer to "specific feature" but what you'd want to append is the option to disable that feature. Perhaps instead:
"If you wish not to use a specific feature, an option to disable it will need appending to the command line used."

And we assume folks know, or can find out, that "+no..." is probably what they want.
