Does the tree of knowledge of good and evil encompass all knowledge?

I was wondering about this part of Genesis: The tree of life also in the midst of the garden, and the tree of the knowledge of good and evil. (Genesis 2:9). Is the tree of knowledge between good and evil how people gain knowledge? Like is all knowledge based on distinguishing the difference between good and evil, or is it more nuanced than that? Does moral discernment form the foundation of all knowledge shown in this passage?
