Where should I install my m.2 drives?

I plan to have two m.2 drives. One with Windows, one with Linux. I'm hoping to only use Linux, but I've had issues in the past trying to switch to Linux. Either way, I think I would prefer to have the Linux drive in the 'primary' slot.

I am running an AMD CPU AM5 processor, which has 24 PCIe5 lanes, but both of the drives are actually PCIe4. The motherboard has three m.2 sockets. The first one is Gen 5, the second one is Gen 4 and the third one is Gen 4 but shares with a Gen 4 PCIe4 slot I do not intend to use, so I'm cool using it for a drive, but it does go through the chip set.

So I figured I would put the Linux drive in the second slot and the windows drive in the third slot. But because Windows is an actual operating system (go with me in that one). I thought maybe it should maybe NOT go through the chipset but instead be in slot 2 and the Linux drive should be in slot one. Slot one should be backwards compatible and since it has 24 lanes, it shouldn't affect the GPU, right?

So which configuration should I use?

Thank you in advance. I hope to get feedback before Lemmy deletes this, which they always do. Never knew how to use Reddit either.
