Strong safety habits in a dorm room
Yes, you can utilize the Ethernet port to connect a router and configure a password-protected network.
If you're lucky enough to have an Ethernet port, consider asking beforehand if they know how to set it up. Then configure a router treating the Ethernet port as your WAN connection. This ensures safety even if dorm firewalls aren't properly applied. During school days, there was an access point lacking security settings—devices could communicate freely. In reality, @DripplessNewt simply made Wi-Fi public and Windows managed most of it. For more control, you can adjust the Windows Firewall to block everything except what you need.
If you're comfortable, I'd configure OpenVPN on their router (or another friend's) outside the college. My router already had an OpenVPN server, so setup was straightforward. When using Wi-Fi at school, I'd connect to the VPN and set "redirect-gateway def1" in the settings to ensure all traffic goes through the VPN instead of directly to the server network. While on the go with my phone or laptop, I'd switch back to my home VPN. Some websites or apps might block the connection, like Spectrum preventing streaming when connected via VPN. If that's an issue, make sure it's configured as public Wi-Fi as recommended earlier.
