Automate additions to grub.cfg

I'm running the latest Plasma 5 and it runs fine. In Eric's install guide when he converted it over to elogind there is one step where you need to "cat /sys/module/nvidia_drm/parameters/modeset" and if the result comes back N (which it did for me) then you need to add "nvidia-drm-modeset=1" to the "linux" lines of grub.cfg. I did and all is fine, however, when I install a new kernel and and grub-mkconfig gets run it generates a new grub.cfg and the "nvidia-drm-modeset=1" bit gets removed. Rather than having to edit the grub.cfg file by hand every time is there a way to modify a file under /etc/grub.d to take care of this? I grep'd 10_linux and see this entry where it adds parameters to the linux line

linux_entry "${OS}" "${version}" simple \
Maybe I'm overlooking something trivial or missing the obvious. Can someone please let me know how to have each newly generated grub.cfg file append the required "nvidia-drm-modeset=1" bit to the "linux" lines for each kernel version in grub.cfg??? Thank you.

In /etc/default/grub include this line:

Then run:
grub-mkconfig -o /boot/grub/grub.cfg
