Hello Raymond Koek,
Unfortunately, it is not possible to change the position of the SKU on the cart page, but you can remove that column using Custom CSS. Please copy and paste the following CSS code to XStore >> Theme Options >> Theme Custom CSS >> Global CSS and check back to your site after clearing the browser cache.
The result should look like this: https://postimg.cc/BXLtfXg4
.woocommerce-cart th.product-sku {
display: none !important;
}
.woocommerce-cart td.product-sku {
display: none !important;
}
Best Regards,
