You'll need to spend more to get the MITX. The best choice is an ASUS ROG Strix B450-I for $138. If you want to save, consider the Asus Prime A320I-K at $93, which reviews say can handle a 3600. There are some alternatives available but they're limited.
These are essentially all mini ITX boards, but they're currently unavailable.
