Change MacBook location?

I live in South Korea at the moment and want to watch a bit of German series, but unfortunately I can't watch all the videos because the message "is not available in this country" appears. Netflix is of course no longer German, which really annoys me. Unfortunately, I don't know what that means, but you can somehow change the region on the hard drive or so that the PC thinks I'm in Germany. Can someone tell me what it's called or how do I do it?

What you are looking for is called VPN, Virtual Private Network. This allows you to hide your IP address, depending on the VPN client, and select a specific country.

Please do not choose a free one, as this usually does not work and was not developed that well. But unfortunately I can't give you a recommendation.
