How can i make the AEM to take the globally installed node rather than installing the node again while deploying the project by using "$ mvn clean install -PautoInstallSinglePackage" as my oroganization blocks installation due to security reasons
You might be referring to an instance running in DMZ (assuming this is not an AEMaaCS instance) on which installation is blocked.
I suspect if you're unable to install the project using maven due to security reasons, then you might not be able to install the project by updating the targetURL to a global node in POM.
You can use cURL commands[0] but not sure if the POST calls are also blocked.
You can repost your query here- https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/ct-p/adobe-experience-manager-community as this seems to be a specific AEM deployment scenario.
