You can't do that specifically with config options but you could
probably submit a scheduled downtime external command for the service.
That definitely feels like a hack though.

The combination of max_check_attempts and retry_check_interval are there
specifically for this purpose. What is nagios supposed to be doing
during this recovery time in your scenario? Is it checking the service
or are you going to just show it down for 30 minutes without checking to
see if it's recovered during that period. Using the combination of
normal_check_interval, retry_check_interval and max_check_attempts
allows for a lot of flexibility. For example, there are several ways to
meet your scenario --

normal_check_interval 5 ;check every 5 minutes by default
retry_check_interval  30 ; wait 30 minutes between checks when not OK
max_check_attempts    2 ; alert after the second non-OK check result

normal_check_interval 5 ;check every 5 minutes by default
retry_check_interval  10 ; wait 10 minutes between checks when not OK
max_check_attempts    4 ; alert after the 4th non-OK check result

normal_check_interval 5 ;check every 5 minutes by default
retry_check_interval  3 ; wait 3 minutes between checks when not OK
max_check_attempts    11 ; alert after the eleventh non-OK check result
