Sure. You need the isowood macro of course, and then I used the following:

#declare P_RoughOak =
pigment {
   P_IW_13
   color_map { CM_IW_05 }
   scale 1/4
}

#declare Fin_W =  //which is basically the default
finish {
   ambient 0.00
   diffuse 0.7
   brilliance 1
   //specular 0.2
   //roughness 0.001
}

#declare N_IW_14 =  //instead of Norm_W (if you prefer)
normal {
   wood 0.4
   octaves 4
   turbulence <0.07, 0.07, 0.4>
   lambda 0.80
   scale  <0.06, 0.06, 0.9>
}
