How to force Siri on HomePod to ONLY recognize my voice and no one else's?

I would like to have Siri on HomePod to ONLY recognize my voice and no one else's voice. Please, I beg you not to misunderstand the question.

I DO NOT want anyone else to be able to access Siri on HomePod. I want Siri on Homepod to only hear my voice and no one else's. So, if a guest says, "Hey, Siri" the HomePod WILL NOT hear. The HomePod will not answer -- it will ignore him/her. The HomePod only hears my commands.

Thank you.
