Waterproof case

We are going to use the Drive AGX on a Formula car where the computer needs to be enclosed in a waterproof case.
Is there any recommendation how to do this?
Is it possible to convert it to use watercooling and if so how may one do that?

Thank you very much

Hardware Platform: DRIVE AGX Xavier™ Developer Kit
Software Version: DRIVE Software 10
Host Machine Version: native Ubuntu 18.04

Waterproof in airtight case would be quite challenging for thermal compare with put it in trunk.
