Can i use different NOC other than 2171 for OINP?

[mayurvd9]

Hello,
Hope you all are doing well!

I am faced with a dilemma
My NOC is 2171, but OINP is considering only NOC 2172,73,74 etc. for scores around 440.
My score is 439

Can i change my NOC to 2173,or 2174 just to get it.
These NOCs somewhat match my job desc, but not entirely like 2171.

So should i do this?
Please advise

Thanks

BR,
Mayur
