My hardware, which is based of the Raspberry Pi CM4 device, requires a device setting in cmdline.txt for the display to work. Currently I have to manually add this to the boot partition, but when I upgrade the OS that setting is lost. It would be great if the Supervisor had a feature to manage cmdline.txt additional parameters.
For reference, this is what I need to add to my cmdline.txt for my display to work: video=HDMI-A-1:800x480M-32@60D
