How to split available bandwidth between 2 primary devices?

[Phate]

Hi all

A friend of mine is a twitch partner and her husband is a graphic designer. They both work from home and husbando often has to download large files for work and/or upload them, which results in her stream dropping frames and buffering etc

Now, their internet connection is 80 down, 20 up, if I remember rightly.

My networking knowledge isn't great. I know basics, but thats it. So, I am wondering. If they wanted to setup something so their bandwidth is split evenly between their machines, so one cannot go past a certain point (lets say 40/10 each) - would this be possible? and if so, whats needed/how involved is it?

Thanks very much!
