ML Classication - Change ratio P output

HI

I am using an ML Classification model. The “Predictor” automatically uses the ratio >0.5 or <0.5 for predictions. I would like to change this parameter, for example :

P (Outcome = O ) > 0,4 Prediction = 0

Obviously, the opposite for prediction 1 (>0.6 instead of 0.5). Is there a way to modify this parameter in the “Predictor”? Or should we use a Rule Engine or Expression after the Predictor node?

Thanks

Br
