Multiplex two displays or use a higher pin count uC?
In general, a chip like this that has a bus interface can share that interface with other devices of the same or different types, as long as each one has a unique "chip select" signal.

For this particular chip, it looks like you'll also need a separate "TE" status connection from each one as well as a separate "CS#", but all of the rest of the interface signals can be shared.
