Best bet is to buy another bag of “non sticky” rice.
One tedious way to do it is to cook up a batch of the rice, then leave it overnight in the fridge uncovered. The next day the rice should be less sticky, but also very dry. Good for things like fried rice, and perhaps congee or porridge (but that would defeat your purpose). But if you reheated it in a microwave (on high, now water added), it will be less sticky, but quite dry I fear.
But really, it’s rice, just go buy another bag and save the Calrose for its intended purpose.
