Keras custom loss function without y_pred and y_true

I am having a problem at hand which optimizes a loss function that is not a function of y_pred and y_true . After going through the Keras documentation , I found out that all the custom loss functions must be a function of both y_pred and y_true.

Is there any alternate way of implementing my kind of loss function in Keras?

No.This is the flaw of keras. If you want to use that type of loss function, then the basic stochastic gradient descent scheme won't work.Many concepts such as batch size will disappear and that will be a substantive change so keras does not allow you to do so.
