Unfortunately, no. There is no way to directly do that as described. You would instead have to change the values in the screenshot to what you want them to display as, and then you would have to convert the values to the originals for your client’s data to work.
If you create a small reference table for your Enum column and you change that from Enum to Ref, you could change the value depending on your employee’s selection.
In addition to advice from Aleksi, you can control diplay name as well.
Follow the guide from Aleksi, create simple table for emum values. Basically two column should be fine.
One is value which is set to key as well.
Then another column is value for display. And make sure to set this display name column as LABEL.
