WooCommerce - Reset product quantity after validation error

Question

I have a variable product that has variations based on a meal selection, like chicken, beef. I also have a custom field called Badge Name. I want the user to be able to add the product multiple times to the cart as a single quantity, with a different variation and/or badge name. So the cart should look like this:

Variation	Badge Name	Quantity
Full Package - Chicken	Tina	1
Full Package - Chicken	Mike	1

I have added a custom validation, verifying that the quantity is 1. If the quantity is changed to 2 then I get the error as expected. However, I'd like the quantity to reset to 1 but it stays at 2. I can't set the max quantity to 1 because I want the user to be able to add the product to the cart multiple times per order. I can't seem to find the correct function for changing the quantity back to 1 on the product page after a validation error. Am I over-thinking this and the answer is right in front of my nose?

Here is my validation code:

function filter_woocommerce_add_to_cart_validation( $passed, $product_id, $quantity, $variation_id = null, $variations = null ) {
// Product id for 2021 Full Package - Online
$product_id_full = 3164;

// If passed
if ( $passed ) {
    // If product is added with $quantity > 1
    if ( $product_id_full == $product_id && $quantity > 1 ) {
        // Set error message
        $message = 'Full Package must be added to the cart individually with dinner selection and badge name for each attendee.';
        wc_add_notice( __( $message, 'woocommerce' ), 'error' );
        $passed = false;
    }
}

return $passed;

} add_filter( 'woocommerce_add_to_cart_validation', 'filter_woocommerce_add_to_cart_validation', 10, 5 );
