You can grab the plugin here:
RPG Maker MV automatically has shadows coming from certain wall tiles. There is no way to turn them off by default. A plugin did come with the DLC pack but it also turned off all shadows regardless. This plugin lets you decide whether or not you want shadows to be on or off by default as well as give you control over whether or not you want to enable/disable shadows for very specific maps and/or tilesets.
