I may be missing something, but it is almost a guarantee that you would not receive a RA in this scenario? eduroam is using WPA2/WPA3 enterprise, so my understanding is that until you authenticate to the network you do not have L2 network access.

Additionally, eduroam uses certificate auth baked into the provisioning profile to ensure you are authenticating using your organizations IdP. (There are some interesting caveats to this statement that they discuss in https://datatracker.ietf.org/doc/html/rfc7593#section-7.1.1 and the mitigation is the usage of Private CAs for cert signing).
