Late 2019 Macbook Air with Intel Core i5 8GB RAM 128 SSD

I have a late 2019 MacBook air with an Intel Core i5. I REALLY want to upgrade this processor to make the laptop just a bit better. Because I just bought it, I really don't want to get a whole new computer. I was wondering if it is possible to replace the possessor. I have heard that the processor is attached to the logic board so I am open to getting a new logic board. If anyone wants to help me out that would be greatly appreciated!
