==>You can get the current product category using the below code.

NOTE: Please do not use the Object manager

<?php 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('Magento\Catalog\Block\Product\View')->getProduct();
$categoryId = $product->getCategoryId();
echo $categoryId;

?>

==>And now get the array of the selected category from your backend and write the login as per the below code.

<?php
$selectedCategory = [2,3,5];

if (!in_array($categoryId , $selectedCategory))
    # code...
    #Add To Quote
}
?>

I hope this is helpful to you!!
