I don't think there is an easy way to change those defines in u-boot
without modifying the code.

An alternative is you could use some text manipulation from an append
recipe. E.g. using sed/awk/etc. A useful feature of the bitbake task
setup is you can append to a task based on an override, so something
like this would work well:

do_configure_prepend_picozed-zynq7 {
sed -i 's/#define.*CONFIG_ENV_OFFSET.*/#define CONFIG_ENV_OFFSET
0x630000/g' ${S}/include/common/zynq-common.h
}
