You can create a group and put events inside that group, when you need to disable events just set the group disable or set group enable again when needed.
Example 1 :
|Group A
|-Events 1
|--Events 2
Player when collisions with X then set Group A Disable
else
Set Group A enable
Example 2 :
|Group A
|-Events 1
|--Events 2
Player collisions with X then set Group A Disable
Player collisions with Z then set Group A Enable
