Hi @rampage 

Let's try below approach.

1. Create a Client Callable Script Include to validate if the current record is a parent incident.

Sample below

var CLIncidentUtils = Class.create();
CLIncidentUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

	isParentIncident: function(){
		var incidentID = this.getParameter('sysparm_incident_id');
		var grIncident = new GlideRecord('incident');
		grIncident.addQuery('parent_incident', incidentID);
		grIncident.query();
		return grIncident.hasNext();
	},

    type: 'CLIncidentUtils'
});

2. Create OnLoad Client Script to hide the Related List Child Incidents accordingly.

function onLoad() {
    var ga = new GlideAjax('global.CLIncidentUtils');
    ga.addParam('sysparm_name', 'isParentIncident');
    ga.addParam('sysparm_incident_id', g_form.getUniqueValue());
    ga.getXMLAnswer(function(response) {
		alert(response);
        if (!response) {
            g_form.hideRelatedList('incident.parent_incident');
        }
    });
}

Let me know if it works for you.
