Define on Project permissions, user can't edit workflow

Hi all,

I have a plugin who create project with parameters define (scrum board, issues, permissions, role). And i want define a default workflow (who added on the plugin and on project when it is created) who don’t be edited by an user. Is it possible ?

I see the parameter VIEW_READONLY_WORKFLOW, can i use it to make impossible the workflow edit ?

Have a nice day,
