In car Nav does not have a filter system however if you tap the screen and select the charger icon in the lower right hand of the screen it will show you a list of Tesla superchargers as well as destination charger locations. If you scroll down the list that comes up the destination chargers are at the bottom and they are lettered in gray on the map.
Non-Tesla chargers you would need to use 3rd party apps such as ChargePoint, Blink or Plugshare.
The PlugShare Web site has filters for nine types of "amenities," including restrooms, dining, lodging, and parks; but not "places of interest" per se. Unfortunately, the Android and iOS PlugShare apps lack these filters, although I believe you can access them on a phone by using the phone's Web browser.
