It's supported as long as you use Google's bootloader rather than a
legacy one, but you're still stuck with either a 30-second boot delay or
hitting ctrl+d and there's no way to install your own keys without
disassembling the machine and physically disabling the write-protection
on the firmware. It's certainly more hostile than any UEFI Secure Boot
system I've found.
