That's not an easy question to answer correctly.... It depends . . .
What portion of the built-in restrictions are you trying to bypass?
What aircraft are you flying?
Where are you flying?
Some aircraft can utilize "software tweaks", new software, or an actual Hardware upgrade to override certain restrictions.
One VERY important thing to keep in mind.... even if your aircraft has ZERO flight restrictions from the manufacturer, you, the Operator is fully liable to following all local, State, and Federal laws that might come into play from your actions (land use, privacy, and of course Airspace).
