If you're being laid off I don't know if that works.
It is my understanding that they're going to try to get you to say something on the record or worse sign something they can deny your legal rights over.
Just sign it and do it anyway. Teledyne for example wouldn't pay me a package unless I agreed to never bash them on social media. Never for example call them a crooked tax dodge or worthless parasites that liquidate smaller firms. Or so incompetent I am almost convinced they might be a front of some foreign government to weaken the technology of the US as a whole.

It depends on where you live. Where I live, if they get you to sign it on the spot it's very likely unenforceable as you need time to have legal documents reviewed so you aren't just blindly signing your rights away.
