How to change items under edit tab on user account page? I know how to remove the user tab completely from the user menu with hooks.

I want to know where I can find the template file that render the items under this tab (or where I can edit what to show under this tab) as I want to hide some parts for all users).

I have tried Home » Administration » Configuration » People » Account settings.
But it only changes items on the user account page NOT the edit tab.
If you'd like to hide fields or properties from the user account edit form, you can create a custom module implementing either hook_form_alter() or hook_form_FORM_ID_alter(). The ID of the form in question is 'user_profile_form'.
