I found a Workaround for Android Pie in

Hi,
While searching for alternative for your Vold Mahila module, I stumbled upon this page Blog
I don't have the technical capabilities to do this,
I hope you can revive this module as the author was able to add exFat/NTFS support on android pie

I don't think there is a universal "vold" binary for all system version. in this module, I compile it from aosp 8.1 source code, so it might nit work on pie.you can still use this module in your risk, just delete the api detect command in install.sh.
btw, I use fuse instead of kernel modules so it can run on any version of kernel. in your link he use kernel modules that means these modules can only load in the kernel which compile from same code with the kernel module
