Why doesn't Auto-Model use Parameter Optimization for Deep Learning models?

I opened up a process generated by automodel (Deep Learning with AFE) as I wanted to use it as a starting point and I saw that in the Auto FE step and the train step it does not use the Optmize Parameters operator for optimization. Why is that? I had a similar model with SVM and it did use that operator on those steps.

How does the Parameter Optimization on DL H20 models happens after all?
