是否有办法禁用“隐藏我的公开资料和在线状态功能”个人资料设置?

This should work so long as it stays the last item on that list:

.user-preferences .control-group.other .controls:last-of-type {
  display: none;
}

Beyond that, you can also remove it altogether by modifying the template. All you need is to use this:

<script type="text/x-handlebars" data-template-name="preferences/interface">

</script>

and copy / paste the contents of this file in there after removing line #43

If you modify the template and it’s updated in core, you need to update your template as well.
