TMC2226 SPI Klipper support

Hi Folks, I know we can use the TMC2226 via UART if we use the tmc2209 stepper configs

However, my new motherboard (BTT Octopus 1.1) supports SPI natively and I would like to take advantage of that. Would it be possible to get the TMC2226 into klipper natively with SPI?

No, the Trinamic 2209/2226 chips do not have the hardware to communicate over SPI. Those chips only communicate via UART.
