Hey Shlok

First of all, congratulations of scoring such good marks((86.7%) . To get a seat in Nirma University (in CS) you need to get a minimum of 110 in GUJCET but as you may know the cutoffs change every year so try to get higher than 115 or so to be on the safer side (since you have 86.7% in boards). The competition for CS is high so I wish you all the best!
