Character Model - Selecting Submeshes via a Script

Hi, probably a stupid question but how do I select parts of a character model in a script, for example I’d like to be able to have a variable hold the Crop Top so that I can enable/disable it at runtime. I tried a public game object but from there I can’t drag it into the scriptableobject I want to store it in.

For any that may find this later, I have solved the problem by Instantiating the character on start, this allows me to use the prefab’s meshes.
