How do I hide the inside implementation of a block?

I added a subsystem block to my library and I'd like to make the inside implementation of the block not visible outside the library.

I tried using set_param(gcb,'MaskHideContents','on'), but I can still open the subsystem in the Library Browser and see every block I used inside the subsystem.

I know you can use cm.LibraryBrowserCustomizer.applyFilter({'Library/Block','Hidden'}) to hide a block in the Library Browser, but is there a faster way to make every block contained in a subsystem not visible?

You can try setting the Read/Write permission of the subsystem to NoReadOrWrite. You can know further about the NoReadOrWrite permission in the following documentation:

Hope this answers your question
