I need to implement MFA in my application using username/password and OTP through SMS.  
Is it possible to achieve this in keycloak.

Yes, it’s possible, but not ootb. You have to implement it in your own authenticator using the authenticator spi.  
Have a look here in this example (not from me): [https://github.com/gwallet/keycloak-sms-authenticator](https://github.com/gwallet/keycloak-sms-authenticator)
