How to add permanent kernel parameter?

cat /etc/default/grub 
GRUB_TIMEOUT=3
GRUB_TIMEOUT_STYLE=menu
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=nvidia_wmi_ec"

cat /etc/default/grub 
GRUB_TIMEOUT=3
GRUB_TIMEOUT_STYLE=menu
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=nvidia_wmi_ec"

ujust regenerate-grub and sudo grub2-mkconfig don't work.

This is done with rpm-ostree kargs You can append with --append-if-missing=<yourkernelargument> or open them in an editor with --editor
