Hi you can add it (APDL command snippet) under the contact (as done here - https://innovationspace.ansys.com/forum/forums/topic/contact-pair-command-object/) –

below is an example based on your question - change friction values and temps, as needed.

TB,FRIC,cid,2,,ISO     ! Activate isotropic friction model
TBTEMP,0.0         ! Define first temperature
TBDATA,1,0.0          ! Define coefficient of friction at temp 0
TBTEMP,100.0         ! Define second temperature
TBDATA,1,0.2          ! Define coefficient of friction at temp 100

TB,FRIC,tid,2,,ISO     ! Activate isotropic friction model
TBTEMP,0.0         ! Define first temperature
TBDATA,1,0.0          ! Define coefficient of friction at temp 0
TBTEMP,100.0         ! Define second temperature
TBDATA,1,0.2          ! Define coefficient of friction at temp 100.0
