There's a pull request in our kernel tree (https://github.com/raspberrypi/linux/pull/6545) that simply adds SPI_NO_CS to the list of supported modes for the DW SPI controller, as used by the Pi 5 family. I suspect this isn't going to be sufficient to make it work, but it is worth a try.
After backing up any important data, run "sudo rpi-update pulls/6545" to install a trial build of the kernel with that change.
