                    "Action": "db-upgrade",
                    "ForcedApplyDate": "2024-08-12T01:57:32.560000+00:00",
                    "OptInStatus": "next-maintenance",
                    "CurrentApplyDate": "2024-08-12T22:00:00+00:00",
                    "Description": "Required upgrade to mysql 8.0.35"
                },
```

It seems you've already opted-in for the "db-upgrade" maintenance action, scheduled for the next maintenance window. Unfortunately, you cannot undo or defer this immediate opt-in.

Here are a few options to potentially delay or remove the pending maintenance (i recommend the first option):

1. **Contact AWS Support**: Work with Support to see if they can make an exception or provide options to delay the maintenance.

2. **Create a new DB instance**: Consider creating a new RDS instance with the desired config and migrate your data, avoiding the pending maintenance.

3. **Modify the maintenance window**: Try to change the maintenance window to a more convenient time, though this may not affect the upgrade date.

4. **Upgrade manually**: If comfortable, you could manually upgrade the database engine before the scheduled maintenance.

Unfortunately, once an immediate opt-in is requested, there are limited options to defer or remove the pending maintenance. Your best approach may be to work with AWS Support for alternative solutions.
