Just:

$('#edit-submitted-first-name').removeAttr('required');

Using Javascript:

document.querySelector('#edit-submitted-first-name').required = false;

$('#edit-submitted-first-name').removeAttr('required');

If you want to set required to true

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',true);
});

if you want to set required to false

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',false);
});

Even though the ID selector is the simplest, you can also use the name selector as below:

$('[name='submitted[first_name]']').removeAttr('required');

$('#id').removeAttr('required');
