Is there a way to clear the OPCUA trigger configuration from the losant-edge-agent.toml file from the Losant workflow?

Yes; attached is a simple workflow that demonstrates this. The process is as follows (you will need to adjust this flow to fit your use case):

1. Use an [Agent Config: Get Node](https://docs.losant.com/workflows/data/agent-config-get/) to fetch the current `triggers` configuration.
2. Determine the index of which item in the `triggers` array is the one you want to remove.
3. Set the value of the item at that index to `null` (this is important; you must do this instead of simply removing that trigger config from the array!)
4. Use an [Agent Config: Set Node](https://docs.losant.com/workflows/data/agent-config-set/) to set the `triggers` property to the updated array (with the `null` item at the index of the trigger you want to remove).

Bear in mind this will break any triggers deployed in any workflows that use the config you are removing.
