No, for two reasons:
1. Most supplicants will only allow you to authenticate Either Certificates OR username and password. A few custom supplicants will allow you to do a combination of username and password, smartcard and certificate, etc, but they cost money.
2. Most radius servers like clearpass can only service a single EAP type at a time, but a custom supplicant can make them authenticate one or the other. Highly secure environments deploy this, but they are expensive to deploy and complicated to install and maintain.
