Ram Support fo G3 - 3579?

Hi, I want to ask you about ram upgrading for G3.

I've just bought G3 3579 with 16GB ram with i7-8750H - GTX 1060 MaxQ model. Actually It was really hard to find a ram support guide on the website.

Anyway, I want to upgrade ram to highest value as much as possible. First of all, this CPU i7-8750H can address 64 GB ram. I think the mainboard limits it to 32GB (because it has 2 ram slots). To upgrade 16 to 32 is not necessary for me for a while, but i want to ask about,

many vendors have started to sell 1x32GB nodules DDR4 2666 MHz CL19 1.2v SODIMM.

Any possibility theese modules work? Or is it possible to make them work with bios update which Dell may publish in the future?

So is that a hardware limitation or can be solved with bios update? Any idea?

Thank you.
