Is it possible to edit lightning:inputField ui attributes via recordUi?

Question

I need to make the Name field required on the lightning:recordEditForm. So I tried its onload event and recordUi parameter. But it didn't work. So I am wondering if it's even possible with recordUi?

component.cmp

<lightning:recordEditForm objectApiName="myObject__c" onload="{! c.handleOnload }" >
    <lightning:inputField aura:id="field" fieldName="Name" />
</lightning:recordEditForm>

controller.js

handleOnload: function(component, event, helper) {
    console.log("handleOnload");
    const recordUi = event.getParam("recordUi");

    recordUi.objectInfos["myObject__c"].fields.Name.required = true;
    recordUi.objectInfo.fields.Name.required = true;
}

Currently you cannot set the lighting:inputField ui to required. You can however update the CSS file and add the customRequired class to the field and it will mark it as required, I then handle the submit event and check to see if the required fields have been filled in

CSS

.THIS .customRequired{
    font-weight: 400; 
 } 

 .THIS .customRequired:before{    
     content: "*";
     margin: 0 0.125rem 0 0.125rem;
     color: rgb(194, 57, 52);
     float: left; 
 }
