I know my non-volatile copy of the environment is in NOR flash so I use
the command
protect all off;erase <saved env address> +1
But, of course this is specific to NOR flash.
I'm not aware of a way to do this in the general case, independent of NV
environment storage media and redundancy.
I'd be supportive of having a way to do this.

Hi.
I am looking for a command
that discards the saved environments,
and takes me back to the
"*** Warning - bad CRC, using default environment" state.
In my case, the environment data is saved
at sector 0x400 of the MMC device on my board.
So, I can just do
> mmc erase 400 10
But, beforehand, I need to know
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_OFFSET 0x80000
in order to confirm if the above command is doing the right thing.
(If I make a mistake in calculating the offset value,
other data would be damaged.)
Is there a nice command to do that?
