Will custom shell scripts void support?

Hi I'm very concerned about not voiding warranties or support licensing. We have multiple IPSec VPNs on our astaro v8 220 UTM which we monitor VPN connectivity uptimes with Nagios.
I'd love to be able use Nagios event handling to restart a failed VPN but from what I see in the forums I will have to configure sudo access to run a script or two to restart StrongSwan tunnels.
will this void any warranties or support?

Thanks in advance!
