github.com/raspberrypi/pico-sdk@6a7db34ff6/src/rp2_common/hardware_vreg/include/hardware/vreg.h (L26)

I want to set the voltage to 0.80V but realize its not in there.

The datasheet says (Table 189. VREG Register):
0000 to 0101 - 0.80V

Yup, that's also what the comments in https://github.com/raspberrypi/pico-sdk/blob/develop/src/rp2040/hardware_regs/include/hardware/regs/vreg_and_chip_reset.h say. I guess this also means that the VREG_VOLTAGE_MIN in https://github.com/raspberrypi/pico-sdk/blob/develop/src/rp2_common/hardware_vreg/include/hardware/vreg.h needs updating too.

You might not go anywhere with 0.80V anyway - probably won't boot.
