Solution
Using the Tweak Tool, the following VRA tweaks can be applied to silence these alerts.

Storage Disk Latency
t_isEnabledHighStorageLatencyAlert = false
MTU Issues
t_isEnabledMtuConnectionFailAlert = false
t_isEnabledMtuMismatchAlert = false
Malformed Packet Issues
t_isEnabledMalformedPacketAlert = false
