HAI lighting issues regarding Aclara powerline meters

I'm new and didn't see a search option so I apologize if this has already been discussed.

I have two clients who have a HAI system with HAI UPB switches. I'm not sure what revision switches they have either. The problem comes in with the local utility communicating with their meters over the powerline. Whenever this communication takes place, all of the HAI lights with flicker rapidly. The communication system is called Aclara.

Is there any filter or something like a ferrite core that could be installed on the electrical mains to decouple or remove this interference?

TIA
