Openapi: Override parameter description

Is it possible to override description of property from reference object.

-------------Models----------
User:
  description: |
    Represents a User 
  type: object
  required:
    - id
  properties:
    firstName:
      description: The first name for the user. Optional.
      type: string
      maxLength: 50


UserSet:
  description: Represents a collection of Users. No specific ordering is guaranteed.
  type: array
  items:
    $ref: '#/User'

------------ API --------------

Now, my api references the UserSet

responses:
      '200':
        description: Fetched user information for the specified users (by ids or email addresses).
        content:
          application/json:
            schema:
              $ref: '../../../../components/schemas/service-models.yaml#/UserSet'

---- Expectation -----

I want to override description of firstName from User in my API? If not, is the alternative to create a different User with expected description for firstName and create a new Userset?

---- References ---- Is it possible to override the "required" attribute of a referenced parameter in OpenAPI 3? https://github.com/OAI/OpenAPI-Specification/issues/2026

From these links, only the description of referenced object can be modified.
