Can the hash suffix of PlayerPrefs ("_hXXXXXXXX") be disabled?

Hello, we are using PlayerPrefs to store some information, that is supposed to be read by another program. We only give simple names as keys like "TestString", but in the registry it becomes "TestString_h3703777734". This seems to be expected behaviour judging from the docs (https://docs.unity3d.com/ScriptReference/PlayerPrefs.html). But I'm thinking it's maybe just wanted in the Editor because the suffix is only mentioned in the "In-Editor Play mode storage location" section. So my question is: Can this be disabled or might it even be a bug in the Standalone mode? Tested version: 2020.3.15f2, 2020.3.4f1
