Proper Way to Wear Talit

Rabbi- can you please clarify if there are any poskim that allow one to wear a tallit gadol like a scarf and if not, does one need to offer guidance to those who he sees wearing it as such?

M.b. brings machloket.
Olat tamid allows and taz doesn’t.(סימן כא,יא), don’t say to them anything since they have who to rely on
