``opts`` may be NULL or a BSON document with additional command options:

* ``writeConcern``: Construct a :symbol:`mongoc_write_concern_t` and use :symbol:`mongoc_write_concern_append` to add the write concern to ``opts``. See the example code for :symbol:`mongoc_client_write_command_with_opts`.
* ``sessionId``: First, construct a :symbol:`mongoc_client_session_t` with :symbol:`mongoc_client_start_session`. You can begin a transaction with :symbol:`mongoc_client_session_start_transaction`, optionally with a :symbol:`mongoc_transaction_opt_t` that overrides the options inherited from |opts-source|, and use :symbol:`mongoc_client_session_append` to add the session to ``opts``. See the example code for :symbol:`mongoc_client_session_t`.
* ``validate``: Construct a bitwise-or of all desired :symbol:`bson_validate_flags_t <bson_validate_with_error>`. Set to ``false`` to skip client-side validation of the provided BSON documents.
* ``comment``: A :symbol:`bson_value_t` specifying the comment to attach to this command. The comment will appear in log messages, profiler output, and currentOp output. Requires MongoDB 4.4 or later.
* ``bypassDocumentValidation``: Set to ``true`` to skip server-side schema validation of the provided BSON documents.
* ``collation``: Configure textual comparisons. See :ref:`Setting Collation Order <setting_collation_order>`, and `the MongoDB Manual entry on Collation <https://docs.mongodb.com/manual/reference/collation/>`_. Collation requires MongoDB 3.2 or later, otherwise an error is returned.
* ``hint``: A document or string that specifies the index to use to support the query predicate.
* ``upsert``: When true, creates a new document if no document matches the query.
* ``let``: A BSON document consisting of any number of parameter names, each followed by definitions of constants in the MQL Aggregate Expression language.
* ``arrayFilters``: An array of filters specifying to which array elements an update should apply.
