Which AM4 motherboard will allow me to run 2+ NVME's?

I currently have a Gigabyte B550M DS3H AC and it is rubbish for connecting anymore than 1 NVME. The best it can do is 1 NVME and a SATA m.2 drive at the same time.

Finding out how many PCI lanes available to what slot is an absolute nightmare to me so if anyone could recommend a motherboard that could accommodate at least 2 NVME's at Gen 3 speeds or higher then I would love to hear from you. I have 4x Western Digital Black SN850X 1TB NVME's and my CPU is a Ryzen 5600 (Non G and Non X). Thanks.

X570 can support 3 or 4 gen 4, a proper b550 will support one gen 4 and another gen 3, b550m a cut down b550 from the look of it.

According to the manual for your board the second m.2 slot should be capable of PCIe 3.0 m.2 SSDs, although only limited to x2 lanes. Usually it should be 4.0 x4 but it seems Gigabyte decided those lanes instead go to the second x16 slot. If you want to make use of that then a PCIe m.2 adapter will work.

However if you plan to run 4 NVMes with at least PCIe 3.0 x4 then you'll need a new board anyway, and there's a high chance you'll need to use extra lanes from the CPU to run those extra NVMes, meaning the GPU will only have x8 lanes but that will only lose a tiny bit of performance. Does the board need to be mATX?
