Here are the steps to disable workflow model from the drop down list.
1. Go to user permissions module (http://:/useradmin)
2. select the user
3. Expand the directory /etc/workflow/models and uncheck the models whichever you want to disable.
hope it's helps..
Thanks for your answer. But I'm using Maven Vault plugin and I want to deploy to multiple instance. So is it possible to disable those workflows by making a package.
