Not sure if this is the right place but on amd mobos you could add a slotable am5 socket. Maybye due to size constraints it will be only on the 16 but some sockets is better thsn no sockets. If you wanted to you could figure out a way to increase the bay lane count (thinking higher density) and use a x870e chipset (also maybye you could put m.2 slots all over the mobo to use all the lanes) or if you dont want to you could use something like a b650
