Steve,

   The question is "why would you want to?"  Seriously, 
and I think it's been mentioned recently, if it's working 
correctly, the oil thermostat _shunts_ oil to bypass the 
cooler, so that the oil doesn't get cooled until it 
reaches a minimum temperature (160*F?).  Unless your 
thermostat is stuck, such that oil always goes through 
your cooler, your symptom isn't a good reason to disable 
it. 

   One alternative to the thermostat would be controlling 
the airflow through the cooler with a butterfly valve - 
controlling either the inflow OR the out.
