How to Install new module, add code to existing module that requires the new module, and import config for the new module in the same build

I seem to be running into a circular dependency issue in the scenario where my new build has a new module (B), new code in an existing module (A) that depends on the new module (B) and new config being imported for the new module (B).

In the past I have handled this with creating and deploying two independent builds, one where I deploy the new modules and enable them, and in the second build, deploy code that requires the new modules and the config for the new modules.

Is there a better way to handle this?

The change in Module A is that one of the services in Module A requires a service from Module B.

I have already added dependency to the new module B in module_A.info.yml file but that does not help as the module is already installed.

drush en module_b does not work and it gives the error.

The service "module_A_service" has a dependency on a non-existent service "module_B_service". 

The config import that is in the build has core.extensions updated to enable module_B when it is imported but config import with drush cim is failing with the same error as above.
