Dell Inspiron 15 7590 2 n 1

Hello, 

I would like to know if its possible to upgrade the model mentioned above in terms of the CPU processor. It has an Intel i7-8565U with 2 cores. Since I run most of the adobe suite programs on it I would like more power and speed. I like the 2 n 1 functionality of this laptop and find it useful in my field of study. Also, is it possible to upgrade the GPU for better graphics. I appreciate any information you guys can provide. Thank you
