Yes, that's very possible. You basically need to configure a second WAN port, as well as failover.

So the first thing is that you need to choose the interface that you want to connect your second ISP on. Make that interface a member of the WAN zone, and then choose the appropriate mode and configure the needed settings.

Another step is that you need to configure Failover, which is grouped in with Load Balance:

Just as importantly, you need to make sure that you check all of your NAT rules to be sure that you use the correct interface (WAN Primary IP) where appropriate, especially the rules dealing with accessing the internet. That way, you'll maximize availability.
