SoC FPGA design to ASIC

Hey! Has anyone got any experience (I'm not entirely sure if its possible) in moving from an SoC FPGA design to an ASIC? I know you can go from FPGA rtl / netlist to an ASIC but what about the SoC part? Could you license that from the vendor or are you locked into having to use the FPGA https://vlc.onl?
