Nope, unfortunately there's no way to move the SPay 'bar', it'll always be at the bottom of the Home Screen (at least until Android Q's gestures kinda forces this to move elsewhre).
Only options are to either use it or not on Lock Screen, Home Screen, and Screen Off (in your case the 'Home Screen' option is the one that should be interfering.) You can do that from Samsung Pay's Settings in the 'Use Favorite Cards' option).
