Answer:
(Fatwa: 211/252/L=1432)
Probably you misunderstood it. It is related to Asr salah not to Fajr salah i.e. it is forbidden to offer any other nafl salah from dawn to sunrise other than sunnah of Fajr salah.
و منع … عن النفل بعد طلوع الفجر باكثر من سنته (ملتقى الابحر)
Hence, it is not right to offer Salat al-Tawaf after dawn. However, one may offer as many nafl salah as he wishes until one does not offer Asr salah.
