How to turn off type hint in java stream sequences

IntelliJ 2019.2 CE

1. Navigate to: Preferences -> Editor -> Inlay Hints -> Java. Alternatively, press CMD (⌘)/Ctrl + Shift + A, search for Inlay Hints, open the first result, and select Java.
2. Untick Method Chains tickbox

Alternatively, you can increase the count of unique types in streams/method chains from which the type hints will be shown. I.e., if your stream transforms from type A to type B, and then to type C, this would be 3 types. If you set it to 2, hints would be shown for 3 unique types and more.
