Forum can be very helpful with good descriptions. It helps to put the year and model and not just GTX which has been made for the last 25+ years. Also helpful is saying that it is under the hood and not just a pic of a plastic part.
To answer your question for future reference for others:
Yes, under the hood where the 2 fire extinguisher straps are located, you can loosen the 2 8mm screws at the top on the upper plastic panel, don't need to remove them, and pop up the 2 plastic post pins on the left and right side to fully remove the pins, then the cover can be rotated downward and removed giving access to the back of the broken rubber straps for removal.
