How to disable IPv6 in Clear Linux properly?

Hi ClearLinux fellows!
How to disable IPv6 protocol properly according Clear Linux system architecture?

ipv6.disable=1 needs to be added to the kernel commandline.

man clr-bootmanager explains how that is done. Basically, create a file named /etc/kernel/cmdline.d/ipv6.conf and put ipv6.disable=1 in there, then run clr-boot-manager update, and then reboot.

Very much, thank you.
