You might want to see if you can buy parts out of a damaged Giulia Quadrifoglio, so that you can get solid carbon fiber parts that fit properly.
In the USA you can get the service manual from techauthority.com. I do not know if they have the service manual for an RHD Giulia.
Disclaimer: these are not the complete instructions and there is always a chance of scratching or breaking plastic bits when removing them.
For an LHD Giulia the trim around the shifter is relatively easily removed:
Snap out the coin holder in the storage box.
Pop the back of the shifter surround and the front of the storage box up together.
Remove the storage box, disconnecting the E-brake harness as you go (unclear if this is really necessary).
Snap the shifter surround out.
For an LHD Giulia the trim above the glove box is not so easily removed. Some important details have been dropped for clarity.
Unsnap cover at the front right of the drivers footwell.
(unclear why this is needed)
Unsnap cover at far right end of the dash board.
(unclear why this is needed)
Remove 4 screws, then snap out the glovebox
(the manual has a note about what to do with a cooled glove box?!)
(there is a sequence to this removal and there are at least 2 harnesses to loosen)
Remove the right side HVAC vent (unclear why this is necessary, maybe the right most corner of the trim is tucked underneath this vent?)
Remove 2 screws that secure the trim piece.
Snap the trim piece out.
