Performance Goals as LM: How to remove "Include Me"

Summary:

As Line manager, when going to Team Goals Center > Performance Goals, clicking on "Assign Goals" at the end of the page, a box appear "Include Me".

Content (please ensure you mask any confidential information):

I need to hide this field "Include Me". Indeed, when the box is selected, the Line manager received the goals in his performance goals as employee, which is not allowed for employee to assign his own goal.

So we need to hide this field.

Does someones have a clue ?

By VBS, I do not found the variable to put this field in "false", and I do not found another template to remove this section.
