1 x Hyper M.2 Socket (M2_4), supports M Key type 2280 M.2 PCI Express module up to Gen4x4 (64 Gb/s) (Socket M2_4 works with 11th Gen Intel® Core™ processors only)**

Slot M2_4 supports 4x4 NVMe with 11th Gen CPU.

Otherwise you will be limited to Gen3 speeds, which means you should just buy a cheaper SSD.

Reminder, the 3090 FE used two 8-pins and was a 350W card. If they were going to use 8-pins on the 4090, they could have just used 3 at 450W.

It wouldn't hit 600W as the current 4090 does but it would still have more headroom than the 3090 did.
