I'm not sure about that, certainly the government forces this measure on all but there may be a way for android 6 and 7 users. Certainly the government seems happy to play CYA to the max. As I noted earlier 6 irrelevant to my area flood warnings in one hour. All it achieved was me turning my mobile off.
With android 6 & 7 it is easy to set a 'black list' of rejected numbers and as all my warnings came from the same number 044 444 444 it may be sufficient to just 'black list' it.
