Stop one specific pipe with se semaphore file

Hi
On the pipeline registry file, I configured three pipes, but when I´m trying to stop only one, all the pipes were stopped.

The semaphore file (semaphore.reg) that I configured is like this:

ifw.Pipelines.pipe1.Active = FALSE

The current registry file is like this:

ifw {
    ....
    Pipelines {
        pipe1 {
        ....
        }
        pipe2 {
        ...
        }
       pipe3 {
       ...
       }
    }
}

I don't know if I'm doing something wrong or is it possible to do this operation? I'm trying to stop only one pipe in order to save start up time.

Any help will be appreciated.

Regards,
