Question regarding Flashing and Fusing

Hello,

We plan on using SecureBoot feature on the Jetson Nano. I want to know if flashing is possible after we have fused a Jetson Device ?

Yes, and need to use the relevant key file while flashing the fused device.

See NVIDIA Jetson Linux Driver Package Software Features : Security | NVIDIA Docs

And

-u <PKC_key_file> Pathname of a file containing the PKC key used for an ODM fused board.
-v <SBK_key_file> Pathname of a file containing the Secure Boot Key (SBK) used for an ODM fused board.
