Apparently I was incorrect in stating that NVMe boot is not yet supported—this week the Pi Foundation added a new docs page[1] explaining the (in beta) process for enabling NVMe boot on the Compute Module 4, which currently requires updating the firmware _and_ bootloader. Not something to rely on in production yet, and right now it doesn't work with NVMe drives behind a PCIe switch, so this limits some of the utility, but it is good to know it's being worked on!
