How's the FlexVer connector used?

[tle]

I've read about the physical tampering FlexVer tech in the whitepaper however I am unsure how it is actually configured and utilised. Wondering if any guru could show me some examples? Much appreciated

FlexVer modules for Raptor's POWER9 platforms are (at least publically) not available yet...

my inference from the above marketing pdf and article on crowdsupply is that there is an additional fpga board that connects to the flexver connector.

can anyone comment on the availability of these fpga boards?
