About Mac book M2 screen replacement

My mac book screen has been damaged black line has appeared .My Macbook M2 Air model no is A281. What is the provision for the replacement like the only screen or the whole and the cost for replacement in Nepal Authorized Apple service center?

This query is after I visited the authorized service center Gen Next in Lalitpur, Nepal. They told me I need to replace the whole as my hinges are fine , camera is working also I am using half screen to work which is working well. Can you clear isnt there the provision to change only screen for my model of M2.
