Firstly, I note that you should consider whether this should be the correct
practice. E.g., in some environments I have worked in, the requirement is that
unused ports be shut, or that unused ports that are not shut be in a
restricted VLAN, and are only allowed on some switch blades (and configuration
management tools/processes in place to inform everyone of changes that are
made).

Sure, add exceptions for the interfaces, e.g.:
DEVMON:except(if
_stat;ifName;na:Gi11/.*|Gi4/.*|ATM2/0.*|Gi5/46|GI7/1|ma0|CPP*)
If you have a few specific interfaces that you want alarms on, you can do it
the other way, e.g. with (if_stat;ifName;ao;Gi1/.*). Please see the coverage
of the except option in the "USING" file for more detail.
