How to run Nexus IQ scan asynchronously

Hi,
I have 50+ java jenkins build and want to run Nexus IQ scan for these builds. So how can i run this scan asynchronously for each jenkins build? OR how can i run this scan for all the builds in single shot?

My problem is that since some of my build is failing with policy violation but i don’t want to make the build fail due to this violation for sometime. Also i don’t want to change the policy action defined on nexus iq server.

Thanks in advance!!
