Help with support bracket 6750 6800 6900 and 3080 Gaming Trio

All these GPUs comes with the same bracket, after multiple attempts I managed to install it but at any movement of the computer or cable readjustment the tip of the bracket tends to slide inwards and collide against the gpu scratching it. Any idea or way of fixing this?
