What's the hurry? If you have a radiator drain, use it. The only thing you
accomplish by pulling the lower hose is the possibility of damaging the
nipple on the radiator, the hose or the non-reusable OEM clamp. Why take
the risk?

I'll grant you Nissan block drains are less then obvious & the diagrams in
the FSMs to find them are all but useless. The only reasonably usable ones
I've encountered are on Hondas (visible, accessible & not torqued to
ridiculous, useless levels). The only way you're going to see any of them
is up from the bottom. But, as you say, hardly anybody bothers with block
drains. A flush is much easier.

The only cars I've encountered that did not have radiator drains are a
couple of Lincolns & an Isuzu.
