Setting doesn't exist on my os, and I certainly would not approve of a setting that gives people license to do (imo) shitty things to the user experience just because there's an obscure setting somewhere.
It's your site, you can do what you want; it's my browser, I will close tabs that annoy me with extreme prejudice.
(would have added this ages ago if I knew this existed; not a CSS expert, just seeing it now by checking if web has an equivalent of iOS' `UIAccessibility.isReduceMotionEnabled`. neat!)
