This was, amusingly, one of the things I hated about Metroid Dread. I don't like being forced to wait for "oh hey, attention! You can kill me now!" indicators.
It was only mandatory on a handful of bosses, either ones that had you working to expose their weakpoint anyway, like the weird mollusk thing in the water area, or against the Chozo warriors, and they'd automatically put you in the finisher cinematic when their HP was low enough.
