Yes, but remember that all A10 boot-loaders and kernels are
experimental. If you write the boot configuration to NAND and it (or the
boot-loader) has errors, you end up with a bricked device. De-bricking
is possible, but only from Windows at the moment.
a10linux.org has a multi-boot u-boot version:
