Is there a tweak that allows the phone to shoot raw photos?

I have a old Iphone 6 plus running ios 12.5.1
I've been thinking of ways to use this thing,
and I came to the conclusion this is only good for photos,
like a point and shoot, considering this doesn't have apples shitty post processing and over sharpening,
Is there a tweak for this ios version or this phone, that allows RAW DNG photo?

Thank you,
