(Tree creation) How to remove branches at the bottom of the tree?

I’m creating a tree with built-in Unity’s tool. I want to remove branches that grow near the bottom. For example, i want to set branches grow starting point “2 meters and above”.

How to do this?

p.s. Unity 2018.4.

Is it impossible?

Might have responded too late, but if you play with the Distribution curve you can get the branches to only be on the top part of your tree.
