Yes, when a manufacturer decides to force you to accept their crap on your homescreens, whether that's a "feed" or a search bar or some other unremovable widget, the simplest solution is just to change the launcher.
In case you don't know, your home screens and app drawer are provided by an app called a launcher. The tablet comes with Samsung's launcher, and hence if Samsung code the launcher so that one page always has this "feed" then there's nothing you can do to remove it. However you don't have to use the manufacturer's launcher, you can find a different one in the Play Store and use that instead. You'll have to set your home screens up again, but as you are no longer using the manufacturer's app they can't force anything onto your desktops.
