in my region, there is no AWS codepipeline available
and I need a method to deploy my GitHub project to AWS Elastic Beanstalk
is there any suggestion??
If there is not CP, then maybe there is CodeBuild (CB) and you can use this. CB's source can be github.
Subsequently, in your buildspec.yml you would use EB CLI or AWS CLI to "manually" deploy your application to your EB environment.
