cancel an action with delays

Hello,
I’d like to know if it is possible to cancel an on going action.
Lets say I have an action with an instant state and a delayed one (10s)

In the mean time some trigger occurs.

Is is possible to cancel the rest of the execution?

Not possible. Previous discussions, including some workarounds:
