How to limit the bandwith used by Umbrel

Hi there, I’m not a technical person. Just enough to have built a full node on Umbrel after quite some research.

Now, I’ve noticed that sometimes the bandwith taken by my Umbrel is way to high (to the point that using my PC for working from home has become a pain in the neck).

Is there a way to limit the bandwith used? Can anyone ELI5?

For more details, my Umbrel is running on a RPi, connected via Ethernet to the router, and my usage is almost 0 (I just have my wallet connected to it, for those times when I DCA). I have a Windows 10.

Thanks in advance
