How to cap ultra high speed internet visitors to an arbitrary bandwidth speed? e.g. 50mbps max?

Alright, I'm sorry in advance if I posted in the wrong category, but I've been facing kind of a new issue lately. It has to do with the fact that most servers in North America offer 1gbps uplinks. Back in 2010 this wasn't an issue, since most people were on 30mbps links. But today, in 2022, more and more people have this kind of ultra high speed internet connection at home or in their office and sometimes they're even FASTER than the server (more than 1gbps). The size of documents that we host (e.g. MP4 videos) is now larger than ever before too. What happens now is that very randomly, one fortunate website visitor will use almost all the bandwidth for a few seconds. This causes extremely high latency peaks where virtually all other visitors must stare at a blank, loading page, for a few seconds, sometimes upwards 10 seconds... even if it's only 500KB in size. Is there a way with WHM/cPanel to mitigate this bandwidth issue where a single visitor can literally use all the server's bandwidth for 10 seconds and cause 100 other visitors to stare a loading page for that long? e.g. would there be a way to cap ultra high speed internet visitors to say 50mbps max?
