Bluefield3 DPU cannot find server SSDs in ARM core

Hi. I’m using Bluefield3 DPU controller in the JBoF server.
I suppose the SSDs in the server should be seen inside the DPU ARM core, but none of them comes out.
Only I can see is the PCIe switches, ConnectX7, and a built-in KIOXIA SSD.

The Bluefield3 DPU controller HCA includes PCIe root complex, so I’m not sure why ARM cannot enumerate the SSDs.

Is there any additional processes I should follow to enumerate SSDs inside the server?
FYI. The JBoF server I have is Supermicro SSG-136R-4MU32JBF (link)

please have a look at this page for PCIe configuration:
