Thanks for reaching out. While this feature isn’t supported from within Site Kit configurations you can however followthis guide to manually implement for your site.
We also have an open GitHub issue in relation to advanced eCommerce tracking. You can find out more below:

Thanks James for your reply!
Google Ads, in one of its steps, says that I have to integrate this code before the end of the </script> tag where there is the Analitycs integration code (in my case is a Site Kit plugin integration).
gtag ('config', 'AW-XXXXXXXXX');
How can I do to include this code? (or is it already included?)
Thank you so much!
Making such modifications to the Site Kit placed snippet is not supported. You can however remove the Site Kit placed snippet as below:

After doing so you can manually insert your own Google Analytics snippet with whatever modifications you prefer. Site Kit will recognize this manually placed snippet, so your Analytics dashboard within Site Kit should work as normal.
If you encounter any problems we’re here to help.
