I am also interested in this option for the Pico_W. Reading #8906 I found out the following:
In issue #8906 the required changes were discussed to set a hostname in the cyw43 driver code under /driver/cyw43. and in /extmod/network_cyw43.
Also the resulting PR's #8918 and #9058/#9086 changes the cyw43 code in /driver/cyw43/

Currently, however, the rp2 build for Pico_W seems to use the version in submodul https://github.com/georgerobotics/cyw43-driver/tree/2cf328d9e41603405a037a29e081a7d30dd519e6 at /lib/cyw43-driver

(See CMakelist.txt https://github.com/micropython/micropython/blob/master/ports/rp2/CMakeLists.txt#L243-L247 )

if (MICROPY_PY_NETWORK_CYW43)
    string(CONCAT GIT_SUBMODULES "${GIT_SUBMODULES} " lib/cyw43-driver)
    if((NOT (${ECHO_SUBMODULES})) AND NOT EXISTS ${MICROPY_DIR}/lib/cyw43-driver/src/cyw43.h)
        message(FATAL_ERROR " cyw43-driver not initialized.\n Run 'make BOARD=${MICROPY_BOARD} submodules'")
    endif()

I found out that, at least when building your own Pico_W firmware from the actual Micropython Master branch, you can set a default hostname with the flag CYW43_HOST_NAME.

I have simply added in ports/rp2/boards/PICO_W/mpconfigboard.h the line
#define CYW43_HOST_NAME "uPY_PICOW"
