Jetson AGX Xavier Development kit mount to carrier board

I would like to know whether it is possible to take out Jetson AGX from the carrier board of Jetson AGX Xavier development kit. I know it is possible with Jetson Nano Developer kit.
If it is possible to take out the carrier board and attach Jetson AGX to a new carrier board, will Jetson support external carrier board(other suppliers) in such a scenario and work flawlessly as it works with the carrier board it comes with ?
Reason want to attach a new carrier board is that the carrier board of Jetson AGX Xavier’s operational temperature specification is from 0-35C, my application is looking at temperature specification exceeding this range on high side and low side (below zero and above 35C)
Appreciate any help here
Looking forward to receive feedback

Hi sridhar,

For other suppliers carrier boards, you will need their customize BSP to support their boards.
Not sure what kind of support you require, but we can as consultant to help you resolve the problem.

Any suggestion on carrier board which supports PCI x8. My intention is to use the follwoing NVIDIA MCX512A-ACAT ConnectX-5 EN Adapter Card 10/25GbE Dual-Port SFP28 PCIe 3.0 x8 Tall Bracket ROHS R6
