Cut up the creepvines and go in with a prawn suit to kill the stalkers

A: I kinda need those stalkers for stalker teeth

B: I don’t have a prawn suit yet.

You could relocate

Pick up the drones, take apart your scanner room, rebuild it somewhere else, ad now you have 4 drones.

I don't think there's much you can do besides killing them or relocating your scanner room.
