How to hide the inside implementation of the masked block in simulink library ?

The inside of the masked block in simulink library can be made hidden by changing the attribute 'MaskHideContents' to off using the following command. set_param(gcb,'MaskHideContents','off')

However, it can be turned on by switching it to the original state. Is it possible to hide and lock the inside of the masked block permanently? After the delivery of the simulink library to the user, I don't want the contents of the masked block to be visible.

Create a protected model; see https://www.mathworks.com/help/rtw/ug/create-a-protected-model-using-the-model-block-context-menu.html and https://www.mathworks.com/help/simulink/ug/use-a-protected-model-in-simulation.html

Alternately, use Simulink Coder to generate code for the item.
