Edit: to be a bit clearer about what I’m saying: There’s no indication that before these accidents an airline buying the optional AoA disagree package got extra training to tell them about handling MCAS. And therefore it’s not clear that if these planes had this package they would’ve been saved. The pilots would’ve had a new warning light but not known that it means they need to disable MCAS because there was no training to that effect. If anything I assume the pilots being unaware of MCAS would only think an AoA disagree light impacted autopilot, which is separate from MCAS and disabled at these times. They would still have needed to identify the trim and MCAS problem another way. (Now it is a different matter since everyone knows it’s there.)
