Sure lots of ESS based devices implement the hardware interface to ESS chip volume controller and other chip options. Prolly Topping, Gustard and others. I2S devices include Audiophoinics 9028/9038 and Allo Katana.
IIRC to do DSD volume the ESS chip like other sigma/delta chips converts it to a PCM-like format as part of its internal processing and does volume attenuation on that format before shipping to out to the analog stage of the device.
