Currently there is an option to select predefined styles for carousel, but we have only one option, as you can see here: https://git.drupalcode.org/project/ebt_carousel/-/blob/1.4.0/src/Plugin/...
Talking about UX perspective, if we have only one option isn't necessary ask the user to select, so I think we can set this field as disabled (or remove is better)
I was wondering if we have a plan to create different styles in the future, so I think that's but for now that we have only 1 option I think we can set the field as "disabled" to be clear for the end users
