How to manage beard as a sikh teen

Yup am a Sikh guy and my beard is like I have a lil moustache.. and like then beard about 2 to 3 cm long hair across cheeks and chin and I dont wanna trim.. I guess I wanna but yk the religion thing and my parents gonna kill me how can I manage this cuz I look awkward in whatever I wear.. I used simco and stuff but still it looked awkward to me atleast cuz im 18 and people say im 25 or something.. should I trim? Ik we shouldn't change ourselves acc to other people but most sikh guys I see are having trimmed beards plus I have also observered or ig heard in a stereotypical manner that girls also dont like beards again leave the girl part for now cuz thats a different thing altogether cuz i wanna look good for myself first... just tell me how to manage would love to know!!
