Chhattisgarh swami vivekanand technical university offers M.Tech in various branches like CSE, CE, ME etc as you can check the complete list by going through the below link -

Also, BHILAI INSTITUTE OF TECHNOLOGY BHILAI HOUSE, DIST., DURG CHHATTISGARH and RAIPUR INSTITUTE OF TECHNOLOGY CHHATAUNA, MANDIR HASAUD, G.E. ROAD, RAIPUR are considered to be decent to pursue M.Tech but both of them dont offer M.tech in CSE so I would suggest you to give Gate exam and get required score so that you can get admission in IITs, NITs and GFTIs.

Good Luck!!!!
