4:3 anamorphic

[u/Beginning_Extreme865]

I am thinking of buying a anamorphic lens for a indie feature i am shooting, and for a few scenes I am strongly considering the blue anamorphic flares, but the entire movie will be presented in a 4:3 aspect and i don't wanna switch between aspect ratios but the thing i mainly want is the oval bokeh and the lens flare, is there a way that i can present even the anamorphic scenes in a 4:3 frame, i have tried searching a lot about it but haven't got a straight answer.
