Switching the DAC display on the streamer main Touch Display


In my new network Streamer project, based on windows mini pc, I would like to integrate a quality DAC based on ESS 9038pro.
From my point of view, the best solution is to buy a stand alone S.M.S.L DAC. su-9, disassemble it and integrate the components inside the large case of my DIY steramer 2.0. even if the DAC board, display, button controls, remote control and USB module are on the network.

My problem is that my Streamer already features a 12.6” 1980x515pix wide touch display.
Is there a way, even a complicated one, to drive and/or switch the DAC display to the 12.6” display, even in PIP?
