StrictHostKeyChecking is already enabled for connections to exporters. Why would you want to disable that?

by "Enable" I mean being able to modify it :) In my setup exporter runs on a gateway device paired (1-on-1) with device under test (there is an isolated network between), coordinator also hosted on a separate server. When I try to reach video stream through dockerized exporter it throws strictHostKeyChecking error for exporter host, meaning I would need to add exporter hosts for each pair to my ssh config.
