No, the MSI X570 Ace does not support PCIe bifurcation.
You're just starting out with motherboard tweaks, that's cool! The MSI X570 Ace supports PCIe bifurcation, but you'll need to adjust the BIOS settings. Check your motherboard manual or the manufacturer's website for instructions on how to enable this feature. Also, since you're planning an M.2 upgrade with multiple SSDs, make sure your board supports the necessary slots and configurations before proceeding.
Check the BIOS for a configuration named PCIe Bifurcation, likely near Above 4g Decoding. Confirm you have a dedicated GPU in the system. The top PCIe slot is reserved for x16 operation, the second x16 slot handles x8 and shares bandwidth with it. You’d need to run your card at x4 from the bottom PCIe slot.
