Dell G15 5520 maximum amount of memory?

So I'm wondering what is the maximum amount of memory in Dell G15 5520s laptops.Dell website says its 32GBs while Crucial website says it can be upgraded a max amount of 64GBs.
The specs are:
I7 12700H
16GB (2x8) 4800MHz DDR5
RTX3060 6GB VRAM
Also I have seen some people who have upgraded their Dell G15 5520 laptops to 64GBs of memory from 16GBs.Can anyone tell me if its possible to upgrade the memory to 64GBs?
