There is a small possibility UAE could consider a Giro Vuelta double. It's the easiest double and definitely doable without risking of burning out. At the same time he could become the youngest to hold all 3 GTs, something that Bernal also has the chance at the current Vuelta. That's quite an interesting record, and if he does it next year, it would be a record very hard to beat.
While Tour is the most important overall, Giro and Vuelta are beating Tour in terms of viewership in their own countries and maybe some others as well. If you combine them, the viewership difference is not that large. After already winning 2 TdFs and therefore already well known to TdF public, I think the reach for new viewers would be higher with Giro-Vuelta. You would also get 2 big focal points in terms of coverage.
I still think he would go for Tour but going for Giro-Vuelta also makes sense.
