To get an admission to government colleges in Gujarat through GUJCET a student must be the resident of Gujarat so no being a UP domicile you can't apply got GUJCET, but you can positively go for private college out there like,

Aditya Silver Oak Institute of Technology

Ahmedabad Institute Of Technology 

Ahmedabad University 

Alpha College of Engineering and Technology

Hope it helps.
