As mentioned here in the documentation, some settings can be added or modified inside the window.SnipcartSettings object.
Found on loadCSS:
Setting the
loadCSSoption tofalsewill omit loding the CSS assets for Snipcart.
It looks like this setting isn’t working nor interacting at all with the default installation script which I copied from very first installation instruction, as the external snipcart.css file from Snipcart is still being loaded.
Below a copy of the installation instruction + HTML code snippet. Please check the very last (long) line-item before the closing </script> tag in the HTML code snippet where the loadCSS option is missing completely.
To install Snipcart on your website, copy the following HTML code snippet and paste it directly into your website’s markup. As a best practice, we recommend you add it directly after the
<body>element.

publicApiKey: "YOUR_API_KEY",
