How to disable cloud init networking?

Question

I am trying to disable cloud init network configuration. From the cloud init doc, I have to set network-config={config: disabled} in the kernel command line entry.

When I set it in /etc/default/grub:

GRUB_CMDLINE_LINUX="network-config={config: disabled}"

and run update-grub but it gives me the following error:

generating grub configuration file ...

Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub/grub.cfg.new file attached.
done

Looks like it doesn't take a yaml string.

Am I configuring in the right place?

Thanks

Create a file at /etc/cloud/cloud.cfg.d/99-custom-networking.cfg which contains :

network: {config: disabled}
