Hello, @Bas Kling,
Actually no, you can not change the checkout button link to the cart page in the mini cart, as there is no such option in our theme for this.
You can turn ON/OFF the cart button which directs you to the cart page separately in the mini cart from XStore >> Theme Settings >> Header Builder and edit the cart widget/element, and you will find the option as shown in this screenshot: https://postimg.cc/Y4Ng1HCs
