How to store a non-serializable class' object in Room Database?

Question

I am working in Pose Estimation library from Google ML Kit

The lib storing the retrieved poses in a class Pose which contains a array of PoseLandmark class

Now I need to store the Pose class in the Room DB table .

Since , Both classes are non-serializable and not allowing to instantiate objects directly (only ML Kit have access to builders ),

So I unable to write Type Converters to them .

Is it possible to store these type of classes in Room DB (or atleast using new Jetpack DataStore)
