To Chris' reply, here's a video by Rick Beato on what he terms as the most important guitar technique. As you improve, becoming natural with the various ways of muting is a very important skill. Some folks take to it more naturally than others but you want to be mindful of ways that you stop unwanted string ringing. Some of it is making sure that you only strum what you need and others are the various muting techniques.

Don't freak out that you have another skill to learn, eventually that muting thing comes along by using the thoughts of Rick and the stuff Chris said.
