How to programmatically change the data shown in the inspector?

Question

Unity

Unfortunately the question is not from me. On it I will explain as itself understood
I so understood that there is a heap of objects in a hierarchical order. You need to go through all of them programmatically change and save the transform, which can be viewed in the inspectors of these objects.
An example of an inspector window for one of these objects is below. In the screenshot, you need to change the width and height of the Rect transform and save it so that the data will be different on the next launches and uses.
