That’s the whole point of HTTP request methods: it isn’t. GET should never cause such side effects. The entire web is built with these principles in mind precisely so that problems like this don’t happen.
If you want a slower browsing experience feel free to disable prefetching in your browser, but this isn’t a hill worth dying on.
