Not in Vegas.
Bastinado figured out a way to mux multichannel pcm.
Maybe he will check in.

To render 5.1 to DNxHD

In the render dialog check "multichannel mapping" and open the channel selector and pick the surround bus.

In render setup dialog set the number of channels to 6. You will get 6 mono channels in the DNxHD render.

Note, you can't use this to make a surround H.264/MP4 file in Handbrake. HB will see it as 6 different audio streams and allow you to pick only one of the 6 channels. The only way I've found to make a surround MP4 in HB is to render to an uncompressed AVI in Vegas. That works but you need a lot of disk space for the AVI. A lot.

I can select 5 channels and I'm not sure it will render in 5.1 audio. - Logan5

do you mean select 6 channels?
ie: if you only select 5, wouldn't that leave the LFE out?

Thanks Rocky for your help, I did as you instructed.

I've got 6 mono channels.(viewing rendered file in Vegas timeline)

I'm worried that the channels might go to the incorrect speaker channel on their end.
Would I be better off with AC3?
Would that entail using a third party program to mux AC3 into the Avid DNxHD codec?

Thanks again!
