turn off mustresolv​etosignalo​bject programmmatically

Hello everyone, I have a large simulink model that includes many signals in different levels (subsystems) with the 'mustresolvetosignalobject' ON. I would like to turn off this option from all the signals programmatically. I could do it for inports blocks but not for lines/signals. Anyone has an idea how to do this ? Your help is much appreciated.
