Volume control SB touch

Using Intel Core with Rock and SB touch as streamer and converter. Am using the Roon volume control from my Ipad since my amplifier doesn’t have a remote volume control.

Considering to buy a new standalone dac replacing the SB touch, would it be possible still to use Roon volume control from my Ipad if I link the Core machine directly to the dac? Or is the volume function not a Rock but SB facility?
