How to change example format value of datefield in drf yasg (swagger)

Hello im using drf yasg library to implement swagger in my django based app. I have changed the date format in settings.py file to look like this:

REST_FRAMEWORK = {
    "DATE_INPUT_FORMATS": ["%d-%m-%Y"],
}

Now when I try to test my endpoint in the swagger then I get example of date field in wrong format:

{
  "birth_date": "2021-04-27",
}

And when I try to execute the request I receive the error:

{
  "birth_date": [
    "Date has wrong format. Use one of these formats instead: DD-MM-YYYY."
  ]
}

What is expected to receive but it's annoying to change the example date each time I want to use it. Any tips how to achieve the same format in the swagger example?
