Question

Using some sort of admin settings, Is it possibl

Answer 1

In my opinion, you could generate all updates the simplest way:

select
concat('UPDATE ',TABLE_NAME,' SET ',COLUMN_NAME,'=NULL WHERE ',COLUMN_NAME,'=0;')
from information_schema.COLUMNS 
where TABLE_SCHEMA = 'DATABASE_NAME' and DATA_TYPE in ('datetime', 'date', 'time');

Just replace DATABASE_NAME to your DB name, and execute all updates.
