The port is there and working, but there is no info on capabilities as you did not use sudo.
The port address to type into the wizard is 0xe000

That's nice, how is the latency? It might help to isolate the last 4 cores (isolcpus=2-5)if just isolating the last core is not good enough (isolcpus=5)

For spi, open /boot/armbianEnv.txt and edit the following:
overlay_prefix=rockchip-rk3399
overlays=spi-spidev
