As a stopgap, the control panel on those HT VFDs unclips so you can put it anywhere you like (within reason).
If you're not using an ATC spindle then it's not necessary to have the software control the spindle.
You're not technically meant to turn them on at the same time anyway. The spindle should be turned on first and given time to warm up before starting work.
It would be more convenient though... Which is why it's on my "to do list" (and has been for two years).
