Get MSRP from quote item for a variation of the configurable product

[saadgfx97g0fcc]

Currently, I am using the following approach to get the product and then get MSRP.
I am not happy with this approach, Please suggest a better approach Thanks

$sku = $cartItem->getProduct()->getSku();
$cartItemId = $cartItem->getProduct()->getIdBySku($sku);
$loadedItem = $cartItem->getProduct()->load($cartItemId);
$msrp = $loadedItem->getMsrp();
