DisplayPort can't detect HPD, searching software walkaround

Hi,Nvidia team:
We make a custom board, that transfer DP display data by type-C USB.
Because HW design defect, DP port can’t receive cable hot plugin signal(HPD).
Is there anyway in software that I can trigger the DP plugin process, or where is related code?
or do you have any other suggestion?

No, there is no such method. You should fix hardware problem.

DCE firmware is not open source.
