How to expand PCIe interface?

Robotics & Edge Computing Jetson Systems Jetson Xavier NX

As far as I know, the Jetson Xavier NX has one M.2 Key M interface that supports PCIe x4, and one M.2 Key E interface that supports PCIe x1. However, I have three devices that require PCIe x1 interfaces to connect to the Jetson Xavier NX. What should I do?

Please refer to the datasheet and Design Guide in DLC. Jetson Xavier NX brings two PCIe interfaces to the module pins for up to 5 total lanes (1 x4 + 1 x1) for use on the carrier board.
