m15 R6, upgrade my CPU and does it have 2 ssd slots?

I have a Dell Alienware m15 R6 15.6" Gaming Laptop (Intel Core i7-11800H/1TB SSD/16GB RAM/RTX 3070), and I want to know if I can upgrade my CPU? I currently have 1tb SSD and want to know if my laptop has one ssd slot or two as I want to increase my storage space.
