The factory installed firmware was version 00WW_1_130 with security patch from 2019/08/05. I specifically asked the store assistant to check the date they received their stock and requested one from their oldest batch which they got in August. If you want a phone without the new firmware installed, I suggest going to a place that probably doesn't sell a lot of phones (I went to harvey norman in Australia) as they are more likely to have old stock (though the 7.2 isn't a popular model anyway so you could get lucky anywhere I guess) and ask to check the receiving date.
The OEM unlocking switch was disabled in developer options when I first booted the phone, but I followed the advice in CGarz' post
about enabling internet and rebooting to get it to enable. I was careful to disable "install updates on reboot" from the developer options before I tried this.
I haven't downloaded any updates yet, but raghu says I should still be able to until/unless I install custom recovery or root the device.
