there are some questions i don't find method in apis:
1 how to disable the double click on cell day that will create new event;
2 how to disable switch to pre month or next month when click the first row days or last row days
3 how to disable the hover tooltips in the more list like below.
For your option 2, "2 how to disable switch to pre month or next month when click the first row days or last row days", the following ticket which has been requested before should cover it: https://github.com/bryntum/support/issues/3554
