It is possible to activate/deactivate boundary conditions in different load steps in Explicit Dynamics system. However, it is not possible to activate/deactivate contact regions or body interactions in different load steps in Explicit Dynamics system. 

If you have to use different type of contacts for the same contact/target of body/face pair, you may consider using WB LS-DYNA & LS-DYNA Restart Systems. You can use Frictionless contact at LS-DYNA system and then replace it with Breakable Bonded contact in LS-DYNA Restart system.
