Not sure if that affects any other Giant E+ MTBs, and whether that issue affects other brand MTBs too but here is something my brother has found out and solved for his Trance E+:

Because of the rear triangle shape and the hydraulic disk brake rotor size (203 mm), the rear brake is installed horizontally in Trance E+. If you use an MTB rear fender/mudguard, the mud is being deflected, and it falls right into the slit between the calipers during the ride. Eventually, that makes the brake rotor scratched, which is a bad thing.

Here is the brake mud protector as designed and made by my brother out of a piece of thermoplastic polymer:

And here is how it works:
