Update settings for [units of measurements](https://support.bigcommerce.com/s/article/Store-Settings?language=en_US#physical).
The endpoint does not support partial updates. Provide all fields to update global or channel-level settings.
Create channel-level settings, or overrides for a channel, using the `channel_id` query parameter.
To delete overrides for a channel, supply `null` as a value for all fields. A channel then inherits global values.
The endpoint does not support 'null' as a value for global-level settings.
