> `withSchemaUpdateOptions` is only supported with WRITE_APPEND or WRITE_TRUNCATE with paritioned table. This is noted in the documentation:
> [https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryIO.java#L1965]
> When the temp files are spilt to multiple load jobs, the write disposition is set to WRITE_TRUNCATE for the temporary tables in favor of retries.
> [https://github.com/apache/beam/blob/a8a8b3ab1292ff408940ba4430c95bc754341589/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/WriteTables.java#L219]
> And the loading would fail with error
> "Schema update options should only be specified with WRITE_APPEND disposition, or with WRITE_TRUNCATE disposition on a table partition."
