Changing codebook configuration without changing/replacing AAU

5G topic for NSA: I see that for codebook configuration number of antenna ports n1-n2 has changed from four-one to two-two for a competitor operator.
Is it possible to change it without changing/replacing AAU?

It is still 8 csi-rs ports:

My question is this one: is it possible to change the n1xn2 from four-one to two-two just by software, without replacing AAU?

Yes it’s possible.
In Ericsson system there are parameters called i11 restrictions and i12 restrictions to do the adjustment in N1 and N2.

I would understand it if it possible to limit i11 and i12 restrictions.
So for example instead of running i11 from 8 to have it just till 4 so instead of having two -two to have it just one-tow.
But to change the n1-n2 configuration from four-one to two-two just by software looks impossible to me.

Dear, any clue so far for this topic under Huawei?
