Yes, you can obtain a static IP address independently of your internet service provider.

You can obtain a static IP for your game server beyond just your ISP.
The internet connection method you choose determines the public IP address you receive. Only this provider can assign a fixed IP address. ~Note: As an alternative, you might lease a public server with a static IP and set it to route back to your dynamic IP (requiring periodic updates). Or consider services like no-ip, which offer DNS support for dynamic IPs by handling this process.)
A VPN provides a fixed IP address for outgoing connections. A DDNS service lets your ISP assign dynamic IP addresses like a static one, but you must use a FQDN. In most situations, using a DDNS lets you operate a server—something I once did with a mail server. Ideally, avoid connecting to your local IP address. Have you inquired about the price of a static IP from your ISP? In the UK, they generally offer it only for business connections, usually between £1 and £5 per month.
Thanks for the feedback. Yes, I checked with my ISP and it's quite costly, so I might switch providers. Assuming I can get a static IP from AWS and my server is my home PC, there seems to be a possibility. I’m wondering if it’s feasible to route it through AWS without using EC2 or a domain name in Route53. I’m not sure how to do it without those services, but maybe there’s another way? Also, since the app I’m running doesn’t support it, I’ll need a different ISP.
