Export protected model to a previous version

Hello,

I have a model that I want to protect and share with a customer, the model is part of a project and has some dependecies (data dictionaries, reference subsystems). I'm using Matlab 2025b the customer Matlab 2024b.

Is there a way to protect a model and its dependencies in a previous release?

The only way I found theoretically (I have still to try it) is to export the whole project in the previous release and generate the protected model from it... but seems quite cumbersome. Alternatives?
