Pcie nvme ssd

When i flash my Xavier NX with Jetpack 4.5, I am able to utilize the onboard PCIE NVME SSD but after flashing with Jetpack 4.6, it does not recognize the attached SSD. even when I run lsblk in terminal. is there a driver I need to install or Jetpack 4.6 is not compatible with SSD?

Is it even not shown in lspci?

when i run lspci nothing happens

Can you share the result of your lspci?

nothing shows up when i run lspci

Strange, does it connect well?
