Sherri Shepherd can keep talking for a living about anything she wants ... except the identity and location of the woman who is carrying her baby ... so a judge ordered today.

Shepherd was a no-show in court today, but her estranged husband Lamar Sally was there to argue that their entire divorce should be sealed. The judge did not rule on the case as a whole, but did order both sides to stop talking about their surrogate -- either her identity or location. 

As we first reported ... Lamar is concerned a publicity crush at the hospital will endanger the baby. 

Nonetheless, he has revealed the due date is July 28.

Zip it, Lamar.
