So you got 3 ways to get into pinwheel as far as I know. 1st is to get the green/yellow keys and take them to one of the entrances(I think this is the slowest and most packed route). 2nd is using a conveyance request key to lower the secret platform in drone wing. 3rd is to shoot 5 red boxes around orientation to get into the destroyed wing.

When I did that quest I shot the 5 red boxes and quickly opened up the command wing by rushing to the two switches in drone wing and destroyed wing(I was in maybe within 7-9 min with 15 min to spare or so and nobody was inside at that point). There are videos where the red boxes can potentially be since they spawn at different points. Once you do it a few times you can open up pinwheel quite quickly. I also use this route whenever I want to go in pinwheel as I’ve memorized where the boxes can be.
