When we try to install an ARM SNO from x86 HUB using AI/ZTP flow, the node gets stuck inspecting. The node seems to boot into the old installation in the HDD and not the image provided by the infraEnv discovery ISO.
    On checking the bios config, it appears that virtual media (virtual cd-rom) has the lowest priority and does not seem to get updated. Manually updating this boot order and retrying install helps BMH finish inspecting.

    4.18.0

    It is reproducible on `cnfdg45` and `cnfdg37` machine everytime.    

    1. Install ARM SNO from x86 hub using ZTP Assisted Installer flow
    2. BMH does not progress past inspecting
    3. Check for incorrect boot order in bios config
    4. Manually update the boot order and bump virtual media to first
    5. Retry install and node finishes inspecting.

   Boot order remains unchanged and incorrect when BMH is inspecting

   Boot order is automatically updated and node boots into correct ISO. Subsequently, BMH should finish inspecting and provisioning
