CONFIG_ETHPRIME affects only your _default_ envrionment, i. e. what
gets used when the normal environment is not available for some reason
(like corrupted). As long as it remains valid, installing a new U-Boot
image with additional settings in the _default_ environment will not
change anything as the default environment never gets referenced.

Best regards,
