Not start miner on Power On

Hi everyone!
I would like to know if it is possible to NOT start miners when the farm gets powered On. I see there is an option to delay the start using a timer, but no option to NOT start at all.

The electricity gets cut sometimes and the diesel generator starts up… And it is not ready for the consumption xD
So I would like to always start the farms manually.

I’ve seen this topic previously, but the answer was not clear to me :-/

Thanks everyone in advance!
