SOM link training to start from PCIe Gen 4 directly to shorten the time

Hi,

We are using Jetson AGX Xavier/Orin for Automotive product development and PCIe Gen 4 for data transferring.

As we know, the PCIe link training will start from PCIe Gen1 and gradually to Gen 4. However, we need to shorten the time to meet market using scenario. Therefore, is there any way we can change PCIe link training from SOM size to start from PCIe Gen 4 directly to shorten the link training time?
