Yes, it just has to be wired up to do it, I have mine wired to do it and it works!

rev 5.4 board has only one mechanical relay , but it seems that i need 2 one for starting and stopping and the second for directional change. so how do i wire the board with just 1 relay ?

You need one for each direction, at least for my vfd I did, you could one of these:
