It's going to depend on your contract with the module fabricator. For a project I'm on, we are not making special considerations for shipping - the module shop has the responsibility to provide (and clearly mark for removal) temporary supports needed for shipping.
You'll want to check with your project management to see what the contract requires as you won't want to waste a bunch of hours that your client may already be paying the module people for.
