How do I download anything from Nexus Mods?

I want to try out Fallout New Vegas after having watched the TV show, and beforeiplay.com recommends I use a few QoL mods, in particular one for higher resolution screens (I'm playing on a 4K monitor).

So I lookup "fallout mtui", end up on the mod's page, hit download... and am greeted with a screen telling me I need to sign up for an account.

I obviously do not want to create an account on such a shady website, so I tried using a throwaway email... rejected (of course). I then said "fuck it" and tried registering with my real email address... also rejected. "E-mail address is not valid". Well, it is, this is my primary e-mail address, has been for more than 10 years, and I've successfully used it to register on dozens of websites, including Amazon, eBay, various banks, Steam...

I found several Reddit posts about this issues, dating back to several years to a few months. Apparently, registration on Nexus Mods has been broken for very long, with no fix on the horizon.

So it seems it is impossible to download anything from there. Is there a mirror somewhere? Or are all these mods no longer possible to access?
