a processor;
a data processing unit communicatively coupled to the processor;
a management controller communicatively coupled to the processor and the data processing unit and configured for out-of-band management of the information handling system, the management controller further configured to:
obtain a hardware inventory and capabilities of the data processing unit;
based on the hardware inventory and capabilities, generate a firmware capsule for execution during a basic input/output system phase of the data processing unit to cause a secure erasure of contents of a memory of the data processing unit; and
communicate the firmware capsule to the data processing unit during an operating system phase of the data processing unit and cause the data processing unit to reboot to its basic input/output system phase in order to execute drivers of the firmware capsule in order to securely erase contents of the memory.
