ZWaveJS - can I manually mark a node as dead?

I have some dead nodes that will be live again at some point (wall switches that are plugged out by the current tenant in a part of my house, they plug them in again when the winter comes). But I think ZWaveJS is spending time trying to find them because in the ZWaveJS2MQTT control panel I see the spinning circle besides “Protocol info”. I have had a problem with that before on the old OZW, but I marked the nodes as dead in OZW and that stopped the slowdown. I don’t see where I can do that here, I can only heal and check failed nodes, but that doesn’t really help me. They are marked as “Failed”, but I think they’re still holding back the network.

So is there a way to mark them as dead, so I can avoid the system looking?
