These are the warnings that are on the specs page:
4x M.2 (Qty)
M.2_1 Source (From CPU) supports up to PCIe 5.0 x4 , supports 22110/2280 devices
M.2_2 Source (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_3 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
M.2_4 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
4x SATA 6G (Qty)

M.2_1 slot (From CPU)
• Supports up to PCIe 5.0 x4 (For Ryzen™ 9000/ 7000 Series processors)
• Supports up to PCIe 4.0 x4 (For Ryzen™ 8000 Series processors)

M.2_2 slot (From CPU)
• Supports up to PCIe 5.0 x4 (For Ryzen™ 9000/ 7000 Series processors)
• Supports up to PCIe 4.0 x4 (For Ryzen™ 8700/ 8600/ 8400 Series processors)

*The M2_2 slot will be unavailable when using Ryzen™ 8500/ 8300 Series processors.
**USB 40Gbps Type-C ports on the back panel and M2_2 slot share PCIe 5.0 x4 bandwidth. Both run at PCIe 5.0 x2 when a device is installed in the M2_2 slot. You can switch M2_2 to PCIe 5.0 x4 in the BIOS, but this will disable the USB 40Gbps Type-C ports. The USB4 host controller supports up to PCIe 4.0 x4.

Out of curiosity, what generation is the NVMe?

Also, which CPU are you using, that will make a difference.

My specs are 7700x cpu, 2x32gig 6000 ram gskill, RX6900XT, 2x nvme both gen 4. 7200 speed, USB mouse and keyboard, corsair h100i water cooler, 3 sata DVD drives, I would like to use m2_a and m2_d. Just so my video card doesn't cover any drive. The latest bios cause boot loop. Windows 11. I have a 3rd nvme gen 4 7200 speed. 1 drive is Windows other is game, 3rd is supposed to be a back up drive. This is my first MSI board I usually use gigabyte and asus since 2001.

You're safe with M.2_1, M.2_3 and M.2_4
The only problematic one is M.2_2 (shared resources with USB Type-C).
