It's connected to PCI. What makes you so sure that it has no DMA access?

Indeed - iLo is pretty good, but the implementations provided by other vendors have an even worse track record than AMT does.
I think they even excluded iLO when they locked down firmware updates to paid customers just after https://lkml.org/lkml/2013/11/11/653 (they are the one who ported UEFI to RISC-V too!)
Not the same thing at all.
Edit: and trivially removable if you don't want it.
