fuunctions.php

add_filter('woocommerce_checkout_show_terms', 'remove_terms_and_conditions_checkbox_for_specific_category');

function remove_terms_and_conditions_checkbox_for_specific_category($show_terms) {
    // Check if WooCommerce is active and the cart object is available
    if (in_array('woocommerce/woocommerce.php', get_option('active_plugins')) && WC()->cart) {
        // Define the product category slug to check for
        $targeted_category_slug = 'your-product-cat-slug-here';

        // Get the cart contents
        $cart_items = WC()->cart->get_cart();

        $has_specific_category = false;

        // Check if any cart item belongs to the specific category
        foreach ($cart_items as $cart_item) {
            $product = wc_get_product($cart_item['product_id']);
            $product_categories = wp_get_post_terms($product->get_id(), 'product_cat', array('fields' => 'slugs'));

            if (in_array($targeted_category_slug, $product_categories)) {
                $has_specific_category = true;
                break;
            }
        }

        // If a product from the specific category is in the cart, show terms & conditions checkbox
        if ($has_specific_category) {
            return $show_terms;
        }

        // If no product from the specific category is in the cart, hide terms and conditions checkbox
        return false;
    }

    // If WooCommerce is not active or the cart object doesn't exist, hide terms and conditions checkbox
    return false;
}

Place this code in your child theme functions.php file or in the code snippets plugin.

At checkout it will check if any of the products are within a specific product category you define. If true it will show the TOS & privacy checkbox field and statement.
