Can trauma change the type?

We all know that enneagram type is supposed to form as a reaction to an early childhood trauma. As I understand, this trauma is so early that we don't even rember it. I wonder if having another trama in younger years or later in lofe could change your enneagram. As far as I know, instincts can change. So what if you can change your type too? Or what if your type is actually formed by the latest trauma. Like I remeber not having any worries till I got massively bullied wherever I went and now I am absolutely freaking out about what people who know me are allowed to know about me and what not. To the extent that I have multiple accounts for different parts of my life and etc. So what if some kind of trauma happens to me again? Would thia change my motivations again? I mean that makes kinda sense, such major events change worldviews. Or will that just be another layer on my core type that stays the same? If so, is it possible that we all type our traa layers instead of real type?
