How can I set a node's nested (address field) value in a custom submit handler?

Question

I need to clear any data from an address field's values (administrative area, etc.)

In my custom submit hanlder for node form, I know I can use something like below for a standard field:

<?php
  $form_state->setValue('field_alternate_phone', [['value' => 'NEW VALUE']]);
?>

But I cannot figure out how to change the value of a nested address field where the values are something like:

I've solutions similar to below but nothing is working:

$form_state->setValue('field_service_location', [
    ['address' => ['organization' => 'test22111']]
  ]);
