Is there a way to implement lazy loading for kivy app using screen manager and only one kv file for screens?

Question

I have an app I'm developing with many screens, images and I am noticing launch time increasing as I go. I would like to experiment with lazy load/optimization but not sure that it is possible with my current program structure.

I have one python file that passes all screen classes and WindowManager(ScreenManager) working with one .kv that has all my screen layouts, widgets/nav instructions.

Is it possible to delay some of these screens from being loaded without breaking up the kv file? My goal is to decrease app startup time without sacrificing much performance so I expect trial and error but I am just not sure how to start.

Thank you very much for any of your time/help in advance.
