Hello, Ramvidal,
Thank you for the reply.
1/ It appears that this is not a feature of the default WooCommerce functionality. You may need to use an additional plugin to achieve this. You can search for plugins yourself, or contact WooCommerce support for advice – https://wordpress.org/support/plugin/woocommerce/
2/ Single Product Builder > Tabs > you can enable/disable tabs.
We hope this information is helpful.
Kind Regards,
