Iron man in Deadpool 3

So I know RDJ was originally gonna cameo (probably with or in place of happy), I understand why they cut him to not confuse the general audience because of the doom announcement, but was there not a single reference to him, like in the TVA the screens focus on Captain America (probably to help lead the audience into the captain America switch up) and well Deadpool in place of loki in dark world but apart from a couple flashes of iron man on the screens of the TVA why do you think Deadpool never mentioned him?
