Hello, the 3.3v pin is not available in the connectors of the board.
This is mainly due to the fact that the Raspberry can be instantly fried if the the 3.3v coming from the Raspberry PI is shorted to Ground.
Anyway you can always use one of the GPIO pin and set it to High (3.3v), but you need to check the max current you can draw from it (if not wrong is was max 50mA),
Alternatively, the safer option is to use a 5v to 3v buck converter.
