Description:
Environment 
Python 3.9
Django 3.2.16

I define convert_class in  settings.py 
DATABASES = {
    'default': {
        'ENGINE': 'mysql.connector.django',
        'HOST': '127.0.0.1',
        'PORT': ccc,
        'USER': 'ccc',
        'PASSWORD': 'ccc',
        'NAME': 'ccc',
        'OPTIONS': {
            'autocommit': True,
            'charset': 'utf8mb4',
            'converter_class': AAConverter
        }
    }
}

.venv\Lib\site-packages\mysql\connector\django\base.py
line 363
 def get_new_connection(self, conn_params):
        if "converter_class" not in conn_params:
            conn_params["converter_class"] = DjangoMySQLConverter
        cnx = mysql.connector.connect(**conn_params)

        return cnx

actually,  the convert_class will be a class variable of config object.
so.  "converter_class" not in conn_params will always true.

How to repeat:
define convert_class in  settings.py 
DATABASES = {
    'default': {
        'ENGINE': 'mysql.connector.django',
        'HOST': '127.0.0.1',
        'PORT': ccc,
        'USER': 'ccc',
        'PASSWORD': 'ccc',
        'NAME': 'ccc',
        'OPTIONS': {
            'autocommit': True,
            'charset': 'utf8mb4',
            'converter_class': AAConverter
        }
    }
}
