Warranty and stripped screws problem

I’ve been trying to replace a corrupted SSD inside the laptop (blade 15 2019 advanced model) but I ran into two extremely stripped screws on the backplate that won’t grip onto anything. I’ve tried everything i’ve seen online (except a dremel which doesn’t seem safe or smart). Does anyone have any suggestions for how i can get these screws out? Is the laptop still under warranty in this state? Im completely out of ideas and at a loss at this point. Any help at all would be greatly appreciated.
