Please give this a try. I’ve modified your existing code to check whether it’s a product or not. Let me know if it works.
function sv_remove_product_page_skus( $enabled ) {
global $post;
if ( ! is_admin() && get_post_type( $post->ID ) == 'product' ) {
return false;
}
return $enabled;
}
add_filter( 'wc_product_sku_enabled', 'sv_remove_product_page_skus' );
