You should be able to "saveenv" after making your change.

The uEnv.txt that used to be supported was to make it possible to
programatically change the boot behavior from freebsd userland.  That
feature got lost when the uboot ports were all rewritten to use a
default environment (boot scripts and all) for freebsd that is
basically identical to what linux uses.  It's a lot less work for the
port maintainers, but we lost some functionality along the way.
