So is there any artificial way or genetic modification by anything possible for height growth?

???????????: If you entered puberty at the average time & have not grown more than 1cm in the past year, you are likely finished. Extra height requires open growth centers which close in most males at 16-18.If you entered puberty late, an xray of your hand could show open growth centers & you might grow more. There are no special meds,exercises,treatments that would add height if the growth centers have closed
