This is not easily doable. But you can use the expressions to do it with pconvert.
red = Oa09_radiance < 0 ? 0 : Oa09_radiance > 430 ? 430 : Oa09_radiance
This limits the values between 0 and 430. For the blue and green channel do it equivalent.
As additional option to pconvert use the -s option to disable the skip histogram values.
With -s 0,0
nothing will be skipped.
I thinks this will do what you want.
