Engines haven't had coolant drains since the 1950s, so you won't find one, they were there to drain engines in the winter so block wouldn't freeze
Popularity of Anti-freeze/Coolant made that unnecessary

You can remove an "easy to get to" core plug(freeze plug) to drain the block, then replace it with rubber style core plug, for future removal if needed.
Rubber plugs work the same as the metal ones, metal ones are just much cheaper so that's what engine makers use
They are not there to protect engine from damage in case they did freeze, lol, old wives tale, the CORE holes are there so casting sand could be cleaned out after the molten metal cooled down, then the core plugs are put in.
Think about how water freezes, if water froze inside the block enough to push out a core plug then it is already too late, for other places in the engine, if freeze damage was going to occur.
But they still call them freeze plugs :)

Lower radiator hose removal will drain most of the coolant in an engine, then place a garden hose in the upper hose(remove thermostat) and let it flush out the rest

I think he was mentioning the coolant bleeder as in when trying to get all the air out of the cooling system. I'm going through the same issue right now, refilling the coolant and trying to get all the air out of the system. Should I just follow the classic burping instructions on the forum and on youtube?

Loosen the heater hose that is on the highest outlet of the engine, but at the other end of that hose, i.e. the by-pass or the heater core(firewall), and fill, this lets most of the air out of the engine.

Rest will come out on first cool down, reservoir level should drop so top it up after full cool down
