Lock and unlock cash management card

Does the Stessa Cash Management Visa Card issued by Tread Bank have a lock and unlock feature? This is a security issue I would like to see as well as having a Savings account so I don’t have to leave my money in an account that does not have a lock/unlock feature. Also, I do not want the savings account linked to the card, I will transfer money to checking as needed, again safety to secure my money.
I just located the “Virtual Debit Card” in Cash management, this is a start to securing your money.
Thank you for your consideration.
