Recreate/Rebuild Index with Constraint

I discovered that we had a number of indexes that should have been defined as UNIQUE. Prior to a scheduled index rebuild, I had a sequence of SQL that would have dropped the index and then create it as a unique index.

However, the drops generated ORA-02429 errors (cannot drop index used for enforcement of unique/primary key).

Is the solution as simple as dropping the constraint, dropping the index, creating the unique index, and alter add the constraint back in?

I am using Oracle 19c.
