Using surface-to-surface radiation without Kirchhoff's law assumption

Hello,

I wanted to use the surface-to-surface radiation physics coupled with a heat transfer in solids physics to model mutual irradiance in a channel of a specific material. I have the absorptivity and emissivity of the material, but the surface-to-surface radiation physics only allows defining the emissivity and assumes absorptivity is equal.

Is there a way to define the surface absorptivity separate from the emissivity in the S2S physics? If not, is there an alternative way to do this using the geometrical optics physics?

Thanks!
