Display Port API and AUX Transactions

I am a software engineer looking to develop a program that makes the NVIDIA GPU perform read DPCD register data using the AUX channel of DisplayPort. We manufacture rugged displays and I am wanting to do this in order to test and debug our display. There doesn’t appear to be any public interfaces with the NVAPI to do AUX transactions and the I2C-over-AUX transactions are blocked with the available I2C functions. The manufacture of our display port receiver IC had told us that NVIDIA has software libraries available for this, but they are not public and require possibly require and NDA.

Can someone please direct me to right channel to get technical support for this.

Thank you!
