Non annotated methos as nullable by default

Question

Is it possible to configure the IntelliJ or maybe the NullAway to consider non annotated method as Nullable by default?

e.g. The following method:

context.getResources().getString(R.string.app_name);

The getResources is not annotated as nullable or non-null. I think it will be interesting to receive a warning "Maybe it will be null" in those cases, but neither the IntelliJ or the NullAway are telling me that it can be a possible NPE.
