How to identify Header Section in CRM Form?

Is there a way to tell if the section is a header in CRM Form?

We're on Microsoft Dynamics CRM 2016 and I have a requirement to disable all fields on the Contact form when a certain condition is met. I'm using the code below and so far the code is working.

var attributes = Xrm.Page.data.entity.attributes.get();
for (var i in attributes) {
  var myattribute = Xrm.Page.data.entity.attributes.get(attributes[i].getName());
  var myname = myattribute.getName();
  if (Xrm.Page.getControl(myname) != null) {
    //alert(myname);
    Xrm.Page.getControl(myname).setDisabled(true);
  }
}

However the reason I ask, special for header fields, you need to put header_ before the field name in order to get to the header fields. For example header_name. Since our CRM Manager likes to put different fields on the header, it'd be nice to automatically disable the header fields instead of manually change it.

Basically every field in the form has to be in a section except header. So this is helpful in this case as we have to identify the fields in header & disable it.

I have used forEach iterator to check each control and if that control does not have a Parent which is a section - then its a control in header, so disable the control.

Xrm.Page.ui.controls.forEach(function (control) {
            if(!control.getParent()){
              control.setDisabled(true);
            }
        });
