Closing windows by code QGIS 2.18

Im trying to close the window (by code) that appears right after the "add feature" tool is called. This is the window im talking:

This is my plugin code:

    def run(self):
    """Run method that performs all the real work"""
    self.iface.actionAddFeature().trigger()
    # CLOSE WINDOW CODE HERE

Everything i tried closed my QGIS program. Is what im asking possible? If so, how?

Answer

def run(self):
"""Run method that performs all the real work"""
self.iface.actionAddFeature().trigger()

QSettings().setValue(/qgis/digitizing/disable_enter_attribute_values_dialog', False)

Turning "ON":

QSettings().setValue(/qgis/digitizing/disable_enter_attribute_values_dialog', True )

Turning "OFF":

QSettings().setValue(/qgis/digitizing/disable_enter_attribute_values_dialog', False )
