If you need to hide the freidsna dn persons variants then the code in the RAW block will have the next view (but the "Asynchronous Mode" for the "Create Post" block should be disabled):

<script language="javascript">
const aVars = ['PERSONS', 'FRIENDS'];
aVars.forEach(reduce_vars);
function reduce_vars (sItem)
{
$(".sys-privacy-group").children().remove('optgroup[label=' + sItem + ']');
}
</script>
