The likely problem is a lack of driver support for using the T2 as an SSD controller. I don’t think, based on Apple’s white paper, that they did anything to explicitly block Linux from accessing the internal SSD - it just needs to go through the T2 for that.
Hopefully someone is working on the necessary driver support - these laptops are still very new so maybe nobody has gotten around to it yet.
