thanks @danielkza
Since the Zstandard lossless data compression algorithm has been included in Linux kernel from 2017 and OpenZFS since 2020, it feels reasonable that this option should be available in our ZFS-LocalPV Data Engine.

I will track this feature request and see when we can schedule it for inserting into a future release.
