External stepper setup and config

With a Duet2 you have to make compromizes regarding setup-compatibility. It only supports SPI-comms with TMC2660, but they aren't available (yet) in the classic pololu driver footprint. There is a bigfoot TMC2660 with support for SPI-config.
The STM32-port of RRF has some options to mix all sorts of drivers with UART or SPI comms. I hope, the main branch of RRF will pull this mixed drivers option one day. -

i see that it's a "TMC2660-BOB" avalible, but well it's not exactly a plug'n pray option ðĪŠ -
Ok so how about this, to get the TMC2100 disabled when not printing:
Adding a little mosfet that toggles 3.3V to the Enable pin on the driver. Using exp8 / heater3 to activate the mosfet with a macro that gets runned in the start/stop of a print etc.
Or am I missing out on something obvious
