paraameterising the looad balancer for backend pool in the azure

Question

We have load balancer

Need to Add an option called -updateLoadBalancer which can be used to add or remove servers from the load balancer backend pool

the command line

-updateLoadBalancer remove -serverType PPWeb - serverSet Primary

should add a step to the plan that would remove the primary servers from the pp web load balancer.

if that command line is run with the -apply command, then the plan would be executed and the servers would be removed from the load balancer.

the command line

-updateLoadBalancer add -serverType PayerpathWeb - serverSet Primary

should add a step to the plan that would add the primary servers to the pp web load balancer.

if that command line is run with the -apply command, then the plan would be executed and the servers would be added to the load balancer.

-updateLoadBalancer remove -serverType PPWeb - serverSet Primary

-updateLoadBalancer add -serverType PPWeb - serverSet Primary

load balancer details is dynamic, it can be from ppweb ,ppdb based on the parameters

Please suggest how we can achieve this. Thank you.
