I don’t think a finished RISC-V design is available ready to use, you would have to design it from the ground up just as with any other chip. To have such shortcuts, you need to license from Arm.
There are plenty of RISC-V cores available on the market for SoC vendors to license and use. So many that they even outnumber the SoCs using them.
Several RISC-V SoC vendors design their own cores and license those core designs out for other vendors to use in their own SoCs (T-Head, SpacemiT, Tenstorrent), some are focused entirely on core designs that they sell and don’t currently make SoCs themselves (SiFive, etc.), and countless open-source RISC-V cores exist online.
StarFive, ESWIN, and Sophgo are some of the companies that make RISC-V processors/SoCs but which don’t actually “design it from the ground up” since they license the CPU core design from either SiFive or T-Head. Similar to how most ARM SoC vendors license the ARM Cortex CPU cores.

There’s about a zillion FOSS RISC-V cores on opencores.org and elsewhere.
