Hi @saulo
You should be able to remove it by using Javascript like this:
add_action('acf/input/admin_footer', 'my_acf_disable_taxonomy_parent');
function my_acf_disable_taxonomy_parent() {
?>
<script type="text/javascript">
(function($) {
$(document).ready(function(){
$(".acf-field-1234567890abc ul.acf-checkbox-list > li > label > input").remove();
});
})(jQuery);
</script>
<?php
}
Where ‘field-1234567890abc’ is the field key.
I hope this helps. 🙂
