How can I enable GPU 3D stereo output via Displayport?

Hi Nvidia,

I want to extract 3D stereo in DisplayPort, I use Quadro P1000 and QD960 as TX, and I use a FPGA as DP RX. When I use AMD RX 5700 as TX, I can extract 3D stereo in DP, but when I use the two Nvidia GPU, I can’t extract this signal in FPGA. Using AMD DSAT tool, I can find stereo enable button.

But for NV GPU, where can I set this?
