When you trigger that code its always a fairly Large leak. Small leaks rarely trigger the code.
I would just visually inspect your car.
If its not by the throttle body/chargepipe then its One of the intercooler connections which is also easily viewable by just removing lower engine cover.

If your wastegate was failing or malfunctioning its usually pretty loud and rattling.

If all else fails Its under warranty so personally I would just tell the dealer it keeps throwing the low boost code randomly* and to smoke test it.

Takes no time and will give you definitive answers
