some Ideas

[cedricam]

Your program is very interresting.

1. You also could enable/disable IPv6 feature.
2. On each module you have options. The idea is to be able to set all drivers options

modinfo <modules>
options <modules> options1=X options2=Y ...

If it s possibe, to have the default value, and the best value

3. to unload drivers over the grub kernel ex: ipv6.disable=1
   you could use this command :
   grubby --remove-args="argX argY" --args="argA argB" --update-kernel

4. or to propose to add some options to the grub if you have a specific hardware.ex: gpu nvidia, cpu intel,wifi broadcom,...

5. Backup/restore configuration by command line.
