Is there a way to categorize receiving lumpsum money in lieu of alimony a nontaxable event? both parties CA residents

My ex has agreed to pay me some amount so I do not ask him for alimony. Alimony is taxed at the state level in CA. Is there a way to categorize or list this lump sum amount to be a non-taxable event for me?
Can calling it a “settlement amount” keep me from giving State taxes on it.
He will be paying me from savings which is his “post tax”
Any words of advice are appreciated
