Good afternoon pc591f, I hope you're doing well?
While I'm not sure what version of FNMS you're using, if you're on 2019R2+ you should be able to utilise the Inventory Group Settings, here:
https://docs.flexera.com/FlexNetManagerSuite2022R2/EN/WebHelp/index.html#tasks/InvSet-InventoryGroupSettings.html
This allows you to specify through group targets which Agents can communicate with which Beacons.
I hope that helps!
Best regards,
Jack
