I imagine something like “I do not consent to a search nor seizure of any of my property. May I reach into my pocket so I may place my phone in plain view? If my property is going to be seized even against my will, I still want to ensure everyone’s safety.”

Then repeat the no consent line as you place your phone on your dashboard or whatever.

I imagine this means your lawyer will have body cam footage of the double nonconsent and the judge will see you were willing to comply even with potentially unlawful orders so the justice system could sort it out in court instead of someone trying to fight it out on the street.
