PCIe enable power on Jetson Orin AGX w/ Jetpack 6, R36.3

Hello, I am trying to use the PCIe on my Jetson AGX Orin in order to connect 3 Intel Realsense d457 and stream at full resolution. I have purchased two different USB PCIe boards and connected the cameras. The cameras are detected via lsusb but it seems they are not getting enough power to actually run.

What is the actual way of enabling power to the PCIe? I have seen some other forum results, but would like some confirmation that those are the right way to go (they are about 2 years old at this point).

Thank you

Sorry for the late response.
Is this still an issue to support? Any result can be shared?
