Disable vROPS alerts on certain objects

Good morning,

I am in the process of upgrading several ESXi hosts in my environment. They are all managed by the same vCenter but they are spread across multiple virtual data-centers and clusters.

Problem statement:

Every time I reboot one of these hosts, i get a vROPS alert which triggers an email to our operations team. They have asked me to suppress the alerts on these objects while i am in the process of upgrading the host. Is there a simple way to suppress alerts on multiple host at once?

FYI. I am running vROPS 6.4

Thanks in advance.
