Yes, but whether it works or not is subject to all the vagaries Robert outlined in the thread linked above.
It seems apparent that in order for P2P/NVlink to function correctly, there is quite a complex chain of dependencies, (driver, motherboard hardware, correct BIOS configuration of said hardware, number of PCIe lanes, etc), that need to be satisfied in order for this to function reliably.
It’s somewhat disappointing that Nvidia have not emphasised this more and saved a lot of people wasted time and money. I wonder if this is the reason NVLink is no longer offered on Geforce cards, given Tesla/Quadro customers are probably more likely to be buying turn-key systems where this functionality is specified.
Later: You might find the BIOS setting info in this thread helpful.
