Losing weight as a teen through caloric deficit and cardio

Hi I am a 14 year old male who is 85kg and 175cm/5’8. I am very obese for my age but I also acknowledge the fact that I am carrying a lot of muscle underneath. I want to lose weight as google says my maintence is 2700 ish calories(approx). Would it be fine if I at from 2000-2400 Calories a day with enough protein per kg BW and other things like nutrients etc.the reason I ask this are people online are saying that I will stunt my growth by cutting calories. But I don’t want to wait to lose weight as it is an issue affecting me everyday.Also at the same time I don’t want to stunt my growth at my dad is 6 foot 2 meaning I may possibly have good genetics (my mum is 5 foot 5 though😬)

Finally to summarise my main question is will normally eating my 3 main meals a day with appropriate servings and good nutrients like protein aiming for a calories goal of 2000-2400 around nearly 500 calories under maintenance calories- Will this in my teenage years stunt my growth and development (heightwise etc)

I might try talking with a dietician although my mum is saying it is not needed as long as I can focus on getting 3 good meals in a day it’s just these underlying problems which bother me like apparently I’m going to lose muscle and stuff like that . Would a dietician help?

Thanks for listening all help would be appreciated. Sorry if I blabbered for long just been on my mind for long and I’m motivated to make a change

Ps-To add last year I was 96kg so I have lost 10 kilograms but I was mostly eating under 2000 calories and doing cardio like my swimming sessions and karate sessions but when doing this period of weight loss I didn’t feel drained and felt normal so I wouldn’t mind doing it again as it gave me good results in weight loss - the only problem being apparently that is very bad for me.
