prefab: can you exclude a variable from beign tracked?

Can I exclude the scale of a prefab instance from being tracked? Unity already allows prefab instances to have independent rotation and position, can I exclude the scale likewise?

An example: Imagine I have a prefab of a tree that has built in functionality for my character to interact with. My scene takes place in a forest, so there are lots of trees... each tree is an instance of a prefab, and for design reasons, each has a different scale (carefully placed).
Imagine I decide to improve my tree prefab. Thing is I'd have to write some code to reset every prefab of every scene, and I have to make some script to store a scale, and call it whenever the prefab is updated. Both of this I can do with the PrefabUtility, I'm just wondering if there's a better way, and I can just exclude the scale or other variables

How is your tree script structured? Are you using inheritance/composition? Tree is too abstract, so you would usually make it an abstract class and then different kinds of trees like maple tree would derive from tree. Prefabs are just like templates, you define a base template, attach a behaviour to it then instantiate and if there is a need you can modify stuff at runtime. You could also look at composition, so ins$$anonymous$$d of tightly coupling tree's functionality, for specific functionality you could use interfaces.
