I don't agree with how the patch is done, but in theory it is what
RFKILL is all about (after the re-write). However it has to be hardkill
and not a softkill. The softkill is a userspace decision while the
hardkill comes from actually hardware or firmware in this case.

Seems the Dell hardware/firmware is kinda stupid and inconsistent here
and I have no problem solution. However adding a special HID driver with
this quirk might be better anyway.
