It's not a great idea, but I just want to know how to do it from a technical point of view ^_^
I want to make this field not Editable:

(The issue type is Task.)
So I've opened the Screen (Operation type Edit) and I've seen that the Field Story point is not here (I wanted to remove it from the Edit operation)


What should I do to make the Field Story point not editable for the Task issue type?
Am asking for understanding, not implement it on my real project.
