You cannot be sure from the One-Line. You need to know what they serve. Are they Article 700, 701, or 702 loads.
Yes, they are listed as EM panels but you need more information to know if they are legally required or life safety loads.
I have worked on many data centers that the generators all feed Article 702 loads. So just because they are fed from a generator doesn't make them a Legally required or life safety load.
