Was Tirupati Balaji a Jain/Buddhist temple?

[Badri]

Among the 12 Alwars, Periyazhwar, Andal, Kulasekarazhwar, Thiruppanazhwar, Thirumazhisaiazhwar, Poigaiazhwar, Bhoothathazhwar, Peyazhwar, Nammazhwar and Thirumangaiazhwar have done mangalasasanam in Thirumala.

Poigaialwar - 10 paasurams.
Boothathalwar - 9 Paasurams.
Peialwar - 19 Paasurams.
Perialwar - 7 Paasurams.
Andal - 16 Paasurams.
Thruppaan alwar - 2 Paasurams.
Kulasekaralwar - 11 Paasurams.
Thirumazhisaialwar - 14 Paasurams.
Nammalwar - 52 Paasurams.
Thirumangaialwar - 62 Paasurams.
Total - 202 Paasurams.

The timing of the first three Alwars is during late 5th and early 6th centuries A.D. So was this a Murugan shrine before that? Silapathikaram makes a reference to Thirumala and is timed even earlier than 5 AD. Was it "converted" even before that then?
