I have ASUS Zenith II mainboard and Threadripper 3970X, what I have to do to have in Master Ryzen software ECO mode option available?
Have you looked in the PROCESSOR forum? Where this should be posted?

lukx, looking at the Ryzen Master (RM) Quick Reference Guide (QRG), seems like ECO mode is not supported on 3000 series Threadrippers. Please go the RM site and DL the guide. Sorry, enjoy, John.
