We actually use VEEAM witn SNMP traps as well and I noticed them in our environment, but we don't get email alerts on them so we mostly ignore them.
I was looking around for some type of time setting but have been unable to find anything so I am unsure if it is possible. May want to open a support ticket and see if even possible.
There is a way in vmware HA to ignore them for certain intervals when doing VM monitoring, but that isn't really related.
