Here you go. WARNING! You should disconnect the battery before you do anything and take pictures after removing the covers in case you forget what plugs in where. Once you disconnect the wiring harnesses on both sides and push them aside, you will be able to pull the ECUs straight up. Below photos are for 2020 M550i as you mention in your original post title.
