(OP)
I ran a linear buckling study for a structure, and now want to do similar study but make it a nonlinear buckling analysis. What I want to do is described here:

I did the original buckling analysis according to this:

Would it be correct to just include geometric nonlinearity at both steps and run it?

Could I ask why the buckling analysis itself remains linear when I have specifically enabled geometric nonlinearity in the linear buckling step?
