Why does Windows Server convert target path of docker volume to lowercase?

According to https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-containers/persistent-storage ("Named Volume" section) running containers on Windows Server with specified volume means that target path is converted to lowercase.

So, are there any workarounds to prevent it from doing it?
I want to create volume on Windows Server -v unwound:/app/MyData and don’t want it to be converted in -v unwound:/app/mydata
