I've read that the T2 chip also provides the mass storage interface and without documentation or drivers, Linux cannot be run from the internal drive. Devices with the T2 chip can be booted and run from USB connections with the security disabled but not an internal drive.

Yes, that's unfortunate - the lack of drivers means that Linux devs will once again have to reverse someone's proprietary software to develop their own drivers. It's not a fun state of affairs. Unfortunately, Apple is not likely to start fully supporting Linux on Mac hardware by providing drivers and documentation. But the point here is that they haven't done anything technically to prevent you from running Linux.

From what I remember, it acts as a "normal" NVMe device and you can just add its PCI ID and see the disk in Linux…

but in 10 seconds after that it powers the system off because it detects something like an unauthorized OS. Sounds a bit like prevention.
