How to exclude output in pdoResources?

Question

MODX

Good afternoon.
It is necessary to exclude a folder with id 30 and nested resources (it is nested in a container with id 5) in one of the menus; a
call like this

{'pdoMenu' | snippet : [
    'parents' => '5, -30',
    'level' => '2',
    'showLog' => '1'
  ]}

in log 0.0010440: Added where condition: modResource.parent:IN(5,11,12,13,14,30,31), modResource.parent:NOT IN(30), modResource.published=1, modResource.hidemenu=0 , modResource.deleted=0, modResource.context_key=web
and the resource and everything that is included in it is also displayed according to the single resource template.
And one more follow-up question.
It is necessary to display only those resources that are specified in &resources. If it's empty, then we don't output anything.
If &resources is not empty, everything seems to work, and if empty starts to display from parents, if you specify id in parents, then it does not display anything.
