Я понял, что это можно исправить, если я переопределю URL для страницы, на которой отображаются детали модели пользователя. Но я думаю, что есть более правильный ответ.
path('api/users/<int:pk>/', UserViewSet.as_view({"get": "retrieve", "put": "update", "delete": "destroy"}), name="customuser-detail")
