This has been requested for a long time and easy to add.

Just add a button under follow studio with the JS code
"fetch("/site-api/users/curators-in/"+location.pathname.split/[2]+"/remove/?usernames="+document.querySelector.profile-name.innerText,{headers:{"x-csrftoken":/en=(\w+);/.exec(document.cookie)[1]},method:"PUT"}).then(()=>location.reload())"
