Any safe way to use a Google home mini?

I got a free Google home mini from a Google pixel 2 promotion. I still haven’t opened the box because I know of the privacy implications (and the irony of using a pixel 2). Is there a safe way to use the home mini or should I try to sell it?

I’m thinking PiHole or something to help?

Also, does anyone know if any privacy ROMs are available yet on the pixel 2?
