running a service file befor bootstrap function in nestjs

I have create a microService for shearing Proto files (server). and i have module and service for calling this.

now in my (client), i want to call that microservice as soon as my application started. I already use onApplicationBootstrap() in my app.module file. but thats not work, because I use onModule init for my grpc client config in other modules. is there any way to run this, befor any other modules?
