The only way is with an acf/validate_value filter.
What have you tried?
You would do the same query and if it returns no results then you would return an error message.
You would probably be better off using a select field with Stylized UI which uses Select2 and provides a search and then dynamically generating the select values from available users.
Or better yet, a user field.
