I can't fathom someone wanting save scumming disabled. In a table top game you have a GM who is guiding the experience. If you have one player that constantly rolls ones, it becomes a running joke and the GM adapts the experience to make that player have a blast while rolling abysmally. The game systems in BG3 don't care about the feelings of the player rolling 1 every time. They'll just bend that player over the table and have it's way with them. when the failure for rolling is no options in role-playing and no success in combat, what is left? Starting over from where they last saved, which is essentially a forced save scum.
