Shift into neutral… Manual workaround?

I have not had this issue, but prepping for a cross country trip and not finding anything in the manual, but may be missing it...

If your RDX is broke down and clicking the neutral button is failing to put the transmission in neutral, is there a manual workaround if you need to be towed?

Vehicles have had that in the past, but I know we’re getting more dependent on pretending electronics never fail, so maybe manufacturers don’t bother anymore?
