How to change USB3.0, PCIe & SATA Lane Mapping Configurations

I’d like to know how to change USB3.0, PCIe & SATA Lane Mapping Configurations.

According to the “Jetson TX2 OEM Product Design Guide”, TX2 has 6 configurations. The default is #2.
I would like to consider all other configuration (#1, #3, #4, #5 & #6) for developing new carrior board.

Is there a document about how to change it?

– additional question –
Is there any configuration that I can not use at the moment?

Best Regards,

Hello! Does anyone share the dts and cfg’s files for configuration #3? Jetson TX2 (may upload all in google drive directory). I think NVIDIA needs to create a repository where put files for all configurations (#4 #5 #6). Thanks in advance.
