Yes it is possible, you will need to have multiple "widgets" added to cover all the different object and metrics you want to show in your dashboard.
As long as the data/metric exists in Aria Ops, it is possible to consume it in a view and then add this view into a dashboard or report.
For example, if you have a Storage or Server management pack configured, you could show the metric/data from those management pack into your dashboard.
See example below but you would need to replace some of the widgets with the appropriate non-vmware data you want to showcase in your dashboard
