There is scripts/bareboxenv.c which gets compiled for the target when CONFIG_BAREBOXENV_TARGET is enabled. This allows you to unpack the barebox environment device (mtd/partition) to a directory and back to the device after modifying. There is no direct getenv/setenv functionality, you would have to do a manual echo/cat to the variable files.
