How to get values ​​from pdoFetch for editing before displaying them in the template?

Question

MODX

How to get certain values ​​from a database table using pdoFetch and edit them before sending them to the chunk template?
Here is the snippet

$path = MODX_CORE_PATH . 'components/pdotools/model/pdotools/';
$pdoFetch = $modx->getService('pdofetch','pdoFetch', $path, $scriptProperties);
$pdoFetch->setConfig($scriptProperties);
return $pdoFetch->run();

it immediately displays the data from the table, but I need to change it before passing it to the chunk on the site

well, in the template itself

<input type="hidden" value="" name="test">

I need to change the displayed value from the field before it is displayed on the site.
