Use perfcurve to update model threshold?!

Dear Community,
I am wondering how to use the datapoint of OPTROCPT (see example https://www.mathworks.com/help/stats/perfcurve.html, Plot ROC Curve for Classification Tree)
[X,Y,T,~,OPTROCPT,suby,subnames] = perfcurve(species,diffscore,'versicolor');
to update the classification weight of my model. At the moment, I do not find any property to change the current classification value of 0.5.
Does anyone know a solution on this?
Best regards
