Use Google Nest Mini without any google services

Hello Community!

I just started my home assistant journey, lights and thermostats are ordered and i already installed the raspberry pi 4 version.

Now my question: Is there any known way how i could use a Google Nest Mini for example to work with Home Assistant without connecting to google services? I would love to have a speaker + mic system in various rooms but i 100% do not want to have any Google Devices listening to what i want to do. Is it possible to use these devices locally and block their access to the internet and basically just use the Speaker + Mic?
