New users are sometimes unaware of the the options available in Vegas, since some of them are hidden for legacy purposes, or the fact that much of the information on the internet is outdated.
Vegas has always been able to use the DNxHD / DNxHR LE Codecs from Avid, and even work with the Alpha channel. You must install the codec package and enable Legacy Quicktime support in the Deprecated Features tab in Vegas.
Vegas 19 (recent versions) now have full Apple ProRes implementation, I believe; there were a couple of small issues with certain templates since the feature was introduced a while back.
DNxHR should work if enable Quicktime is checked on preferences/deprecated features and the Quicktime plugin is installed. I don't really recommend it though as it's an old 32-bit plugin and has limits to how many clips can be used.

I can confirm that it does work. I just dropped some 4K DNxHR footage on the Vegas timeline and it seems to be playing off the timeline well after enabling that depreciated feature. (I probably already have Quicktime installed on my machine).
Could be a good feature request for a future update to not have to use that legacy plugin to handle this codec.
