Adding Swagger Docs to Django Without Django REST FRAMEWORK

I am working on a Django project and there's requirement to build the APIs without using the Django rest-framework library.

I'm having a hard time figuring out a work around as most available libraries are already tied to the Django rest-framework pip library.

Can someone point me to an example, library or resource for self documented APIs using swagger docs that

supports at least Python 3.7
