It can be found out from the output of ‘sudo lspci -vv’. Look for ‘LnkSta’ of your SSD device. By default, Jetson Xavier NX is configured to get the PCIe link up at the maximum speed supported by the end point (SSD here). So, there is nothing extra required to be done to get the PCIe link up in Gen-2/3 apart from connecting an SSD that is Gen-2/3 capable.
