Hello Aspirant,
According to the category rank you have mentioned in the question you cannot get CSE in any of the top NITs as per previous year's cut-offs but yes you can get CSE in some moderate NITs like NIT Goa, NIT Meghalaya, NIT Arunachal Pradesh and likewise in some other institutions.
Note that the cut-offs are bound to change every year depending upon various factors.
