Unfortunately, it's not possible to get ACF fields from your Shop page in the normal way. However, it is possible using a Code Snippet and PHP Function Return value. I've added a snippet to your Code Snippets plugin that contains the following PHP:

function my_get_shop_acf ($field_name) {
// Shop page ID is 9
$acf_field = get_field($field_name, 9);
return $acf_field;
}

Here's a quick video that shows you how to use it: https://www.loom.com/share/30467ec9892e4b308e281bb999a05b5b. You need to add the function name my_get_shop_acf and then the name of the ACF field that you want to show on the page.
