The backend is going to determine what can be done and I am not seeing that below. There are many option depending on how complex the changes are in that zone in the DR site. If you have a similar IP subnet scheme in a /23 or /24 with the same 4th octet and the backend is a database, then a script could easily zap the A records in that zone. If the number of hosts at the DR site is relatively small, then a script could create/update /etc/hosts entries on the PDNS server and then serve that via "etc-hosts-file=/etc/hosts".
Bottom line, PDNS is very flexible but as an admin, one has to have a basic understandinig of how the parts fit together to take advantage of that flexibility then know something about scripting the parts together to fit a particular need. There's probably dozens of ways to solve this and 10 replies on this thread could give you 9 different suggestions. We need a little more detail though.

Hi there, How do I quickly switch between two different configurations for the same domain? In bind, I would just keep two separate zone files for the same domain, rename the one of the two zone file that I want to be active to be the active zone file for the domain, and reload bind. How is this done in PDNS? Use case: I have a primary colo site for my ESXi host and a DR site with a second ESXi host that keeps current, but powered down, copies of the guests. The guests are my individual host names in the domain. Of course the IP addresses of the guests will be different between the primary and the DR site. When I need to fail over from the primary site to the DR site, I want to quickly tell PDNS to now please serve an alternate set of IP addresses for the same host names. (I am perfectly fine with this being a manual process. I suspect that there exists a fancy way accomplishing a similar goal using LUA records that exceeds the level of complexity that I am looking for). I suspect that this is a FAQ; I am probably just not using the right search terms.
