Is there a way to disable custom dynamic feature from dialplan?

Hello dear community,

Have a question:
If I enable custom dynamic feature from dialplan like:
Set(___DYNAMIC_FEATURES=playmonkeys)
is there a way ti disable it later from dialplan?
For example if I map ‘5’ to playmonkey feature, but later on from a certain point I don’t want it to be triggered when caller presses ‘5’?
Redefining DYNAMIC_FEATURES (Set(___DYNAMIC_FEATURES=)) does not work.

Thanks in advance.
