Let's define you understanding a bit..
Check the definitions for "branch circuit, multiwire".
If the circuit qualifies then there must be a common disconnecting means.
This can be a multi-pole breaker, a handle tie on the circuits involved or another means.
The rule would apply to the individual MWBC. If you happen to have multiple MWBs in one conduit, each would be addressed separately.
(For example, you would not need a 6 pole handle tie for (2) MWBC)

At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.
