There isn’t a Sense setting to do this. The page is coded the way its coded. But you can use Chrome (and I assume Edge)'s built in code inspector to modify the style sheet of the page while you are viewing it. You will have to do this each time. There is probably some type of extension out there to do this for all sites, but I would be wary with extensions as many are malicious.
In Chrome, you can use the inspector to disable that line of code. Since Edge is just basically MS branded Chrome with some tweaks, I sort of assume you can do the same.
Right click somewhere in the device list and choose “Inspect”.
This will open the inspection window. Make sure you are in the “Elements” tab, and then on the right under styles, type in scroll in the search bar and it should find you the code snippets which include the word scroll.
body :: -webkit-scrollbar
and then uncheck
This will turn off the option to hide the scroll bar.
