upgrading RAM on 2015 macbook pro from 16GBs to 64GBs?

Is it possible to upgrade my RAM on a 2015 macbook pro from 16GBs to 64GBs? I am working in After Effects now and whatever setup I have isn't working. I can only preview at a quarter speed and if I accidentally hit play when at full res, my computer freezes. So I would like to upgrade RAM. I know the latest mac laptops have a lot of RAM. Can I upgrade my 2015?
