I’m very tempted to take this on myself but one thing my mechanic said was that when they fill the coolant, they use some vacuum fill technique which prevents needing to do the bleeding technique. I’ve yet to hear anything about this way of filling the coolant (I assume it uses some special device) but very video and post I look at just says to do the BMW bleeding process.

Sure, if you have a coolant vacuum fill device, use it, otherwise use the bleed procedure like has been successfully performed on billions of vehicles.
