Dell Sonicwall SuperMassive 9800 CPU architecture

[clarknova]

I'm trying to find out what CPU architecture the Sonicwall Supermassive 9800 has, and more specifically, whether one might have any hope of installing OPNsense on it, but this information is elusive, and as far as I can tell nobody has talked publicly about trying it.

It appears the rest of the 9000 series uses a Marvel Octeon chip, but not the 9800. Anybody know what's in this behemoth?

(64 cores in the 9800) https://www.sonicwall.com/medialibrary/en/datasheet/datasheet-sonicwall-supermassive-series.pdf

(Up to 32 cores in Octeon) https://www.marvell.com/products/data-processing-units.html
