Does Quadratic Discriminant Analysis has parameters that can be optimized by optimization technique like PSO

I am currently doing a classification project for the fault in power transformer. I tried the classification with QDA and the result was good. And I wish to optimise QDA classifer so that higher accuracy can be achieved. However, I can't find any related parameters for QDA online. Is anyone know what is the parameters for QDA that can be optimised for better performance?
