Using environment variables without pushing .env to the repository

[RSurya99]

When I try to deploy using this on Github actions in my project, I get an error where it can't detect the environment variables I created in my project in netlify.
I have tried other ways like saving environment variables in Github repository secrets but still, the environment variables is not detected.
then when I try to push .env file to the repository, the project runs normally. But I want my .env not to be pushed to the repository, can I do that?
