TrueNAS Mini E remote OS install via IPMI hardware management

[KBPLLC]

I purchased a TrueNAS Mini E earlier this year which is located at my office. While I can access the ASRockRack IPMI remotely, I am unable to successfully mount (via CIFS) and install ISO images. Also located at my office are two Mini XL+ models with Supermicro IPMI on which I can successfully mount ISOs for remote OS install.

Has anyone successfully performed a remote OS install on a Mini E which has C3338D2I-4L motherboard?

ASRockRack documentation is located at https://www.asrockrack.com/support/IPMI.pdf, however it lacks enough detail for me.
