Remove default notification channel from a single alarm


Is it possible to remove from a single alert a notification channel that is a default one? Currently I have a notification channel that I want to apply not for all the alarms, but for the great part of them. The only way I found is applying it alarm by alarm, which is kind of painful in my case as I have a great number of alarms. It could be great if I could apply as default and then remove only from the alarms I need.

Thanks in advance!
