Adding secure device as non secure with OpenZWave

I have a couple of fibaro FGS223 that are extremely slow reacting (it is a known problem of the second switch on the device with openzwave)
I am wondering if adding them as non secure would make things better.

Now the question : how do I add them (I mean non via PC UI but only using the dongle (AEON) as non secure?

If using the dongel I suppose it is enough to say non secure in the popup but the devices are a bit too far to pair them whithout brieinging the dongle close
