Why not?
They manage motors that get to a thousand degrees. They have the tools. All they really need more is the proper parts and the diagnostic software and diagnosis reference. Just like any other bike.
Plausible, but not how it works so far.
And no, mechanics should not be messing with the engine computer settings without the proper software and diagnosis manual. And there's nothing different about any of the other systems on a Energica - the brakes, shocks, wheels, tires, and even chain are just like on other bikes.

Sure, there's nothing magic about EVs, as you say, the rest of the non-drivetrain subsystems/components aren't different for the most part from ICE (like EV cars vs. ICE); however, when disassembling stuff, the tech does need to know what special precautions to take that don't apply to ICE bikes.
I'm sure once e-motorcycles are common enough, the standard training courses by mechanics' schools like MMI
will cover them. They don't yet, AFAICS.
Until then, I expect the manufacturers are providing specific add-on training for already-experienced & certified techs.
Obviously anecdotal, but out of curiosity, I asked my ICE bike shop (they only maintain bikes, don't sell any) whether they'd be willing to work on an EV bike, if they had the service manual. The answer was absolutely not, beyond tire repair/mounting. They don't want the responsibility.
Incidentally, a kind soul (*) sent me an Energica service manual a few days ago. There's a bunch of EV-specific gear tool that are required to work on the bike, including insulated gloves & shoes that have to meet specific int'l standards, insulated hand tools ditto, test leads & multimeters etc. that have to meet others and so on.
That pretty much exhausts what I have to say on the subject
(*) anonymous because Energica regards it as confidential.
