GeForce GTX 770M - Not good enough?

System Requirements Lab (Can you run it?) states that my laptop is sufficient in all areas except for the GeForce GTX 770M. It shows that I have 3GB for the graphics card but that Squad requires 4GB. I'm not a tech guy and I purchased this Alienware laptop assuming that it would be more than sufficient with 16GB of RAM and an Intel Core i or AMD Ryzen with 4 physical cores.
Is there any workaround that could allow me to get more out of this laptop, or am I simply going to have to purchase something else?
Thanks guys.
