BFCL can it test the different tool_choice mode?

While BFcl is good for checking the tool benchmarking, does it also validate the "tool_choice" feature at all?

BFCL uses the default level of tool_choice that the model provider sets. For most models, that's auto.
If you want to experiment with different levels of tool_choice, feel free to add that corresponding parameter in the query method in the model handler (eg, _query_FC or _query_prompting). This should be a straightforward modification.
