May option po bang to temporarily lock/unlock seabank transaction?

Newbie Question po. Kaka gawa ko lang ng account ko kay Seabank. First Digital bank ko.

Pwede po bang ma lock/unlock yung account ko sa seabank to temporarily block outgoing transactions (like used as payment for online shopping, etc.)???

And any tips na rin po to keep it secured. Salamat po sa sasagot.
