hello developer244,
please note that,
the default fuse value of BootSecurityInfo was burned (by manufacturing) to 0x1E0.
you may refer to Jetson Orin Series Modules Fuse Update Field Services Bulletin for the details, this apply to ALL Jetson Orin series modules.
see-also Topic 344840 for reference.
disk encryption key (sym2_t234.key) is also in the EKS image,
you’ll need to download JP-6 public release sources, running the gen_ekb.py python script to re-create eks_t234.img with your keys.
see-also Topic 270934 to enable disk encryption with a custom key.
furthermore,
according to developer guide, Burn Fuses with the Fuse Configuration file.
we recommends burning all the fuses you need in a single operation.
