Upgrade Options for “HP Envy 16-h0000” secondary m.2 ssd slot

Hi,

I’ve been searching and not finding any clear information about the secondary m.2 ssd slot in my laptop.

I found some indication here https://support.hp.com/us-en/product/hp-envy-16-inch-laptop-pc-16-h0000/2101086015/model/2101251631/document/ish_6507941-6507994-16

…that the secondary slot would accept a 0.5 or 1 TB NVME 2280 m.2 ssd but there is no mention if that would be a hard limit or if you can actually put a larger hard drive in this slot.

The primary slot today has a 2TB hard drive and I would love to put a 4TB drive in the secondary slot for a total 6TB disk space.

Is there anyone who has tried and been successful putting a 4TB hard drive in one of these laptops?

Best regards,
