There's not an interface for it. There's just ffc parameter
'quadrature_rule' (parameters['form_compiler']['quadrature_rule'] or
Measure(..., metadata={'quadrature_rule': rule}) in DOLFIN) with valid
choices: 'auto', 'default', 'canonical', 'vertex'. See
ffc/quadrature_schemes.py for reference.

As a workaround you may edit this file to add a new rule you need. You
may also need to edit _attach_integral_metadata in ffc/analysis.py to
add a new valid rule there.
