At some point they upgraded the U-Boot that comes with NetBSD; so the modern one works even better. But I'm not sure about USB and NVMe support. I expect it works but I haven't tried either.

Nowadays (2025), there's the solution of flashing RK2AW on the SPI alongside U-boot
Megi made pre-bootloader/menu that will check if there are bootloaders on the SD card or on the eMMC and those will take precedence, other wise it has 2 backup copies of U-Boot next to it.
So you can flash that on the SPI, and if something goes wrong in the U-Boot you flashed, or if you merely need a different U-Boot for a different OS, you can simply pop a SD card with it and it will boot.
See here for a package containing rk2aw, opensource U-boot, and U-boot with Rockchip's binary memory initialisation:

It won't let you boot multiple operating systems on the same media, but it will let you boot from any device. You easily flash a good U-Boot over the Manjaru one without affecting Manjaru itself.That makes sense—keeping a solid U-Boot on eMMC gives flexibility without messing with SPI flash.

The one that I use which comes with NetBSD (and can probably be sourced other ways) doesn't have a "menu" but it does have a command interpreter that you can invoke by pressing a key when prompted.
