Is there an option to choose different dielectric material in stack-up? If so, how can i check levels of signal attenuation depending on the dielectric layer chosen?

Yes, You can check the signal speed in different layer wrt to different dielectric material(based on dielectric constant(DK) and Loss tangent). You may have to use an integrity simulation tool to see the attenuation.
