Decouple client (browser) from Vue frontend and Python backend running on Kubernetes containers

Question

I have a Vue frontend application that runs on a Kubernetes container. This application communicates with a backend server running on a different Kubernetes container. The frontend Vue application uses Webpack and injects the full application into the client (browser) storage. Due to this, the browser (client) is the one that is doing the fetch calls to the backend. I can see this on the developer console, network tab. Due to security reasons, we want the browser (client) to interact only with the Kubernetes Vue frontend and be the internal frontend application the one that does the calls to the backend. Is there any way to achieve this with Vue, or is there any framework that works with Vue that allows us to do this easily?

Thanks

I expect that the client does only calls to the internal Vue frontend and that no backend calls are done by the browser
