3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Andrew, in Chrome, go to
That will give some clues as to the webgl support of your graphics processor and Chrome browser. Check the same website's report in Edge browser. You should be able to figure out what webgl extension is not supported in Chrome. Sometimes there's a Chrome flag that can be set to enable whatever webgl feature is unsupported in Chromes default configuration. Good luck!

Aha! you already tried that, right?
Post the psecific webgl error you get in Chrome, there are many variations of webgl errors

You haven’t provided enough info to the forum for others to help you. God helps those who help themselves. 2 of your 3 links did not work. I don’t know what topics you are trying to link to.

The “stigviewer” link regarding disabling WebGL says, “Specifically, web pages cannot access the WebGL API”, so if that’s your problem, it is not a question for the CesiumDev forum.

If you have disabled WebGL, you have disabled CesiumJS.

Good luck. I’ll see if I can help someone else.

Looks like there was a followup posted in that thread, maybe you will have some luck with that one.
