LRD System in Boeing 737 MAX and potential cause for concern in case of Engine Failure

Recently watched a YouTube video regarding the LRD system in Boeing 737 MAX aircraft, which is used to reduce severe vibrations in Engines in case of failure. The video explains that this activation has potential cause of toxic smoke in cockpit as well as cabin of the aircraft, with a lethal concentration of smoke in cockpit under a minute in some cases.
