Prevent replication of ALTER commands

I am using MariaDB 10.0 multi-source replication for a specific use case.

For security reasons, I would like to prevent ALTER commands on master to replicate (such as CREATE, ALTER, DROP...) whatever user run these commands (even root) but of course let SELECT, INSERT, UPDATE, DELETE commands to replicate....

I do not want to use SET SQL_LOG_BIN=0|1 on client side. In fact, I never want to replicate schema modification.

In practice, I wish I could revoke alter permissions to my replication user (who currently has REPLICATION SLAVE permission)

Is there a way to achieve this?
