how to secure erase Jetson device

Hi,

I need to erase internal eMMC 64 GB and external NVM memory in my jetson AgX Xavier hardware which is flashed with linux for tegra flavour of ubuntu 20.04 focal

Theere no steps for secure erase on the vendor NVIdia website.
They have some documentation link for security features as shown below

https://docs.nvidia.com/jetson/archi.../Security.html

I want to know, if there are any particular steps to complete secure erase my memory eMMC and NVM.

Thanks.
