How do you bypass this question or add a flag that auto answers this?

Because I am trying to write a script, and this question keeps stopping the process of rsync since there is no way to answer this in the script when prompted.

Set the StrictHostKeyChecking option to no, either in the config file or via -o.

Use e option of rsync to pass options to ssh:

-e "ssh -o StrictHostKeyChecking=no"
