Set "description Tab" In Product Page Collapsibled/close

I want to set description Tab in product page collapsibled/close as default at mobile view. Is there any easy way to do?

There's a condition in the template (from memory) that excludes the 'description' tab from being hidden. You would have to remove that condition for the class 'hidden'.

No, there is no such ability out of the box
