Yes, but legal maneuverings are incredibly sensitive things, and anything officially entered into the public record becomes evidence. It's generally not a matter of silently capitulating, but if you want to fight back and have any hope of winning, you have to play by the rules.

I'm in exactly the same situation and it's incredibly frustrating, but the alternative is to open your mouth and potentially undermine your legal defense. About the best you can do is to fight the lawsuit to the best of your abilities, but that unfortunately requires that you route all public communication through your lawyers.
