welcome!
as i always say: best way is to NOT edit the template, so you will keep getting updates, but ADD some instructions that will customize your experience.
Instructions:
1) go to HFS, virtual file system
2) right click on the home/root
3) properties
4) diff template
5) past this text
[+]
<script>
$('#actions button:last').remove()
$('#files :checkbox').remove()
</script>
6) ok
be sure you are using the latest HFS version
