Can you change your heraldric symbol?

In Crusader Kings 2 you could modify your dynasty's banner/heraldry. Is that still possible in Crusader Kings 3?

It is not possible to do so in the base vanilla game.

Furthermore, even creating a Cadet Branch to your Dynasty (which generates a new Heraldric symbol + Motto combo) is culturally appropriate, but gives you no options.
