ML agent for recognition od prefabs in AR foundation

Hi Guys! AI in unity is something new for me, so I’d like to ask if something like that is possible:
I have an app where in AR I display different 3D models (I prepare in advance prefabs in editor out of obj files exported from some CAD software). These models are some kind of boxes with doors. The doors have different dimensions. Is it possible to use somehow ML agent to recognise in this prefabs these different doors to interact with them (for example switching them off)? Now During preparation of prefabs (after importing from obj) I search in model the part with door and rename it manually for “door” and after that I can than in code interact with it by searching children with this exact name. I want to avoid such manual job and recognise them automatically. Do you have some recommendations for me in which direction should I go to solve it?
