Hide/Disable radio button in grid

I have a grid where wanted to remove the 4th option for row 11. I have been able to hide it, but it seems it actually still allows it to be selected if someone clicks in that blank area. Below is the code I am currently using.

Further, is there a way to set the radio buttons on this 11th row to be unselected if they have been clicked?

<script>
$(document).ready(function(){
	$('#QB2_r11_4_graphical').closest('.clickable').removeClass('clickable');
	$('#QB2_r11_4_graphical').addClass('HideElement');
	$('#QB2_r11_4_graphical').closest('.mobile_select').hide();
})
</script>
