Is it possible to get direct admission in DAIICT gandhi nagar with 58% of marks in 12th board..?

It is unclear as to what direct admission means. If you mean without JEE Main, then I don’t think it’s possible. DAIICT admission is done on the basis of scores in JEE Main or GUJCET. The admission process is conducted on two levels -

1. All India Level: JEE Main Scores
2. Gujarat State Level: For the Gujarat category, the candidates have to apply through ACPC.

As far as the 12th percentage is concerned, I don’t think there is any fixed percentage so you might get admission with 58% marks.
