Does RocksDB speak NVMe directly?

> High-performance storage engines. There are a number of storage engines and key-value stores optimized for flash. RocksDB [36] is based on an LSM-Tree that is optimized for low write amplification (at the cost of higher read amplification). RocksDB was designed for flash storage, but at the time of SATA SSDs, and therefore cannot saturate large NVMe arrays.

From this slightly tangent mention, I am guessing not.
