Disable competing network boot options and remove PXE retries so the selected DPU remains the sole network boot target.

This looks aligned with the GB300 boot-loop issue we saw.
Non-blocking recommendation: add regression coverage for the GB300-specific behavior here.
In particular:
- DPU boot option already first, but competing Pxe/UefiHttp options still enabled
- is_boot_order_setup returning false until non-target network boot options are disabled
- Lenovo GB300 LEM0001 PXE retry count set to 0
The behavior is subtle because the previous early return looked correct unless the enabled boot options were also considered.
