Performing nafl salaah before the fardh of Fajr

Q: After the Fajr Azaan one is only allowed to perform the 2 Sunnats. If we performed our 2 Sunnats of Fajr after the Azaan at home then when we enter the Masjid: 

1. Can we perform 2 Rakaats Tahiyyatul Masjid or will it fall away? 

2. Can we perform other Nafl Salaah during this time before the Fardh Salaah commences?

A: 

1. Tahiyyatul Musjid cannot be performed. 

2. No.

And Allah Ta'ala (الله تعالى) knows best.
