I haven’t found that to be true of cheap mice and keyboards, or I have to do a certain key combo every time it loses power. I usually end up desoldering the LEDs, but sometimes that makes it stop working so I have to resolder them and put tape around them.
for keyboards and mice, that would depend if it came with software, if it did, it probably has an off setting (e. g my old redragon mouse did, and that was like a 12$ mouse like in idk 2016?) keyboard definetely would be hard if it was a really dirt cheap keyboard.
all do digitally, some do physically.
and it should theoretically be simple to make a physical switch off the adressable header if you wanted a physical switch.
