3.3TT Whining noise from under the hood 3.3tt

[singe_suspect]

Hey guys, first time posting. I checked everywhere and couldnt find anything regarding this. I own a 2019 AWD GT1 with 113k miles, about 30% of it is city and 70% is highway driving. I recently have started hearing a whine underneath the hood that is louder on cold start and increases in pitch with the rpm of the engine, especially when in park or neutral. Could it be a pulley or a pulley bearing? Im hoping its not the alternator, since dropping the engine isn't exactly something id enjoy doing. Anything helps. Thank you guys!
