A4988 Without Motor Connected?

I know that it will destroy the A4988 chip if you connect/disconnect the motor while powered up, but is it OK to power it up when the motor isn’t connected at all? The reason is that I have 4 carriers on my board, and sometimes, I want to troubleshoot by disconnecting one of the motors without unplugging the corresponding A4988 carrier board.
TIA!

Hello.

Yes, it is okay to power them without motors connected.
