AM5 motherboard featuring three rear USB-C connections.
Asus offers a "ThunderboltEX 4" PCI-E adapter, though it only provides two USB-C ports. It's unclear if this setup fits your mini-ITX configuration without a riser, which might undermine its purpose. Many lesser-known manufacturers produce similar PCI-E cards primarily in USB-3 now. So, no. There aren't many reasons for makers to invest in a 3-port USB-4 board with an APU. Still worth considering, though—you could use two external USB-C drives for games and an external GPU to enhance the APU, and share the GPU with others having comparable builds.
