Hello,

You can create a preset via Theme Settings -> Settings presets and define the condition for the specific product: https://prnt.sc/0yLeD52j2rwR then edit the preset and navigate to Single product -> Tabs and define additional tab: https://prnt.sc/h8dP6Wm-KYnF so as a result, that defined tab from preset will be available for the product that is mentioned in the condition.

Here is our article on how to use presets: https://xtemos.com/docs-topic/theme-settings-presets/

Kind Regards
