If I understand correctly, you used Alembic's "autogenerate" feature to create your migration script. This feature compares the table definitions in your application with the table definitions in the database and then generates a script to alter the database to match your application.
You can instruct alembic to ignore certain objects in the database using either the "include_name" or "include_object" hooks: https://alembic.sqlalchemy.org/en/latest/autogenerate.html#controlling-what-to-be-autogenerated The first example there ("Omitting Table Names from the Autogenerate Process") is probably what you want.
