Provide option to disable Build executors for Jenkins master when starting service as input and in configure system it should not be editable when the Jenkins service started with this option.

If we able to do this we can achieve multi-tenant feature, so that we can block build executions on the Jenkins Master considering load & security issues
I have configured the Jenkins like below at different ports(8080,8081,8082) and different JENKINS_HOME

/etc/alternatives/java -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins8081 -jar /usr/lib/jenkins/jenkins.war --httpPort=8081

Configured with Apache Server Reverse Proxy to map each Jenkins instance with each DNS entry.
