Users wishing to build their own customized NVIDIA® BlueField® OS image can use the BFB build environment. See this GitHub webpage for more information.
For any customized BlueField OS image to boot on the UEFI secure-boot-enabled DPU (default DPU secure boot setting), the OS must be either signed with an existing key in the UEFI DB (e.g., the Microsoft key), or UEFI secure boot must be disabled. See "Secure Boot" and its subpages for more details.
Contact NVIDIA Enterprise Support for information on the installation of Linux distributions other than Ubuntu.
