Removing devices from Nest Hub

Hi, I’m recently using the Google Nest Hub with my Homey.
Homeydash and casting my snapshots from my ip camera’s works well.
Question:
When I couple the Homey with Nest Hub all my devices are listed in the Nest.
So when a guest is calling “Hey Google, switch off all devices” my whole Domotica system goes down.
So I will exclude or remove several devices from the Nest Hub.
Is this a known problem and does anyone know a solution to it?
Thx
