Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use. No negative effects could be observed when setting all four. Setting SERIO_QUIRK_NOMUX or SERIO_QUIRK_RESET_ALWAYS on the Clevo N150CU and the Clevo NHxxRZQ makes the keyboard very laggy for ~5 seconds after boot and sometimes also after resume. However both are required for the keyboard to not fail completely sometimes after boot or resume.
