Opposite of LateUpdate()

Hello everyone,
I want that every frame the first thing that happens is script A of Object x, and then the other objects will follow. How can I do that? Or is it even possible? I searched in the internet about the opposite of LateUpdate but I couldn’t find something. Sorry that my problem isn’t discribed very well because I don’t know how to describe it better.
Thanks for help

After a while I looked in the Internet I found a solution… a very bad solution. Here you can see the order of the different event functions and I saw that FixedUpdate is before normal Update. So now I use FixedUpdate like normal update. If somebody has a better solution pls write it in here but for now it should work.
