Is it possible to cut out parts from The middle as well as beginning or end of an mp4 using Vegas Pro 18, without re-rendering the final product all over again? I will not be changing or editing the actual video aside from cutting out sections I don't want. Is this possible without time consuming rendering or is that required?
No, Vegas is an encoder, not a muxer. I use a paid solution called Videoredo. There are also free versions, all having their own features and limitations.
You want ffmpeg. While command line, it's nearly perfect for this application.
for example
ffmpeg -i "C:\Vegas Projects (c)\Hummers\Source Clips\GX030242.MP4" -ss 00:00:00 -to 00:00:15 -c:v copy -c:a copy output.mp4
Timecode is hour:minute:second
This cuts out the first 15 seconds and saves it into output.mp4 without remuxing.
I do it a lot with long DJI Osmo files to cut pieces off I don't like in order to save the remaining on my computer before bring it into a NLE like Vegas. Therefore is for my use MP4 tools enough, the outcom has exact the same MediaInfo as the original file.

Those paid Vegas plugins allow trimming media files without re-encoding:
