The most reliable method is to check your specific aircraft. Flight-tracking sites and some airline apps show the aircraft registration close to departure. You can search that registration on StarlinkFlights.com.
The aircraft that operate YV3991 have not been checked for Starlink, so we cannot rate it yet. That is not the same as confirming they don't have it. Check back as more aircraft are confirmed.
No rating can guarantee a specific aircraft. Airlines swap aircraft for maintenance, operations or schedule changes, so an equipped aircraft can be replaced by one without Starlink on the day. A high rating means the evidence favors Starlink, but it is not a guarantee. On the day of departure, check the airline's gate display or app.
