EBF Baby growth

My son was born weighing 10lbs and since then he’s gained 2.2 lbs. (he’s 3 weeks old tomorrow). His new weight is way above his curve and off the charts so I was advised to feed him less. He’s EBF and I feed on demand, these are his averages from the last week:

Based on that am I really overfeeding him? I also thought you couldn’t overfeed a breastfed baby in the first place... should I worry about his weight? And if I do less than 8 feeds a day won’t my production decrease? This doctors made me really doubt what to do so if there are moms in a similar situation I’d love to know what you did!
