Close a project programmatically without saving changes?

For certain operations in CI, when we run things and try to close them, a prompt comes up noting that there are unsaved changes and asking if we want to save or discard them. In CI of course no one can see the prompt and so the job times out. quit force doesn't seem to help, nor does bdclose('all') since that seems to act on Simulink systems and models, as opposed to projects.

Is there any way to programmatically close a project, even if it has unsaved changes?
