Can a 4-switch buck-boost be reversible?

enter image description here

The base scheme seems symmetrical but I did not find any reversible design.
Do you have an exemple of such a design?

Yes, it is inherently bidirectional, but for it to work, the circuit in charge of driving the FETs must support it. If that's the case, it can control current or voltage on one side, or the other.

Many such cases, here's an example from TI.
