Typically ISPs maintain a limited catalog of supported modems. It seems unlikely a device like this exists—they wouldn’t prioritize it (such functionality is rare). The PC would need to manage DHCP, firewalls, etc., which can be cumbersome. Stick with a standard modem and router for better performance.
Routers and modems generally consume less energy than a computer. If your PC fails, you won’t have internet access to obtain a solution. Certain routers let you run open-source firewall tools with adaptable options.
