addkcmdline is not working

[sujit-jadhav]

I am using xCAT Version 2.16.5 and trying to provision rhel8.8 and given the addkcmdline="R::biosdevname=1 R::crashkernel=155M,high R::crashkernel=72M,low"
But it is not updated in cat /install/autoinst/node1|grep kernel parameters
neither it is present in /etc/default/grub on compute node after provision of OS.
However, it is present on /tftpboot/xcat/xnba/nodes/

I want to know does addkcmdline option work for a node. I tried updating node definition and osimage as well, but nothing is helping out. Any suggestion on this?
