Help #linux #nixos people running on #apple #t2 #macmini hardware!

I've got this 2018 Mac mini, and I cannot get the onboard wi-fi to work for the life of me! I know this is one of those pain in the ass t2 models. And likely has a Broadcom chipset. But this usually works great with these settings.

I even tried t2 fedora spin that even worked out of the box on a T2 MacBook air.

But nothing works on this POS. Any ideas?
