Product Layout Hooks

Hi,
i have construct a custom plugin to hide add to cart button and prices conditionally and everything is working fine. But my code is stop working if i enable a custom layout for product page.
Can you tell me what action should i use so my code will function with custom product layout?

Here is a part of my code that is working when custom product layout is disabled.

/** Modify product page when non-purchasable or hide price & cart are enabled: hide price and/or add to cart button */
add_action('woocommerce_before_single_product', 'gb_npwp_modify_product_display');
function gb_npwp_modify_product_display() {
    global $product;

    $not_buyable = get_post_meta($product->get_id(), '_not_buyable', true);
    $hide_price = get_post_meta($product->get_id(), '_hide_price', true);

    if ($not_buyable === 'yes' || $hide_price === 'yes') {
        remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30);
        if ($hide_price === 'yes') {
            remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_price', 10);
        }
    }
}
