How to privatize Apples Siri assistant?

I am looking for any methods to add privacy to Siri. I do not use apple products but it appears their voice assistant is the most privacy friendly option of the mainstream brands. How can I privatize/anonymize the smallest apple device with siri for daily use. Such as an iPod or iPhone jailbroke or not, or homepod device. I do not have the time to do a lengthy setup. I need plug and go for the most part as I am overworked already. I am using this for voice reminders, to do lists, the basic stuff, asking questions. Thanks.

Edit: Besides locking it in a sound proof danger box, using a voice changer as input, hard wiring on its own little danger spot on the network, fake account, pi hole, and VPN. Any realistic ideas?
