Issues getting anaconda to aks for network with kickstart

Hi all
I am trying to get the installation to prompt for the network details on booting and loading the system.

the redhat manual says I should add asknetwork to the boot command line for the kernel. however, when doing so it has no effect and I am never prompted for the IP address details.

I have tried asknetwork and inst.asknetwork and neither work.

is this supported on rocky and if so can somebody advise how it’s meant to be done?
